 ## Why I built Super Graph?
 
-I have a Rails app that gets a bit of traffic. While planning to improve the UI using React or Vue I found that my current APIs didn't have what we needed. I'd have to add more controllers and ensure they are providing the right amount of data. This required designing new APIs and making sure they match what the webdevs need. While this is all to common work I was bored and there had to be a better way.
+Honestly, cause it was more fun than my real work. After working on several product though my career I found myself hating building CRUD APIs (Create, Update, Delete, List, Show). It was always the same thing figure out what the UI needs then build an endpoint for it, if related data is needed than join with another table. I didn't want to write that code anymore I wanted the computer to just do it.
 
-All my Rails controllers were esentially wrappers around database queries and its not exactly fun writing more of them.
+I always liked GraphQL it sounded friendly, but it still required me to write all the same database query code. Sure the API was nicer but it took a lot of work sometime even more than a simple REST API would have. I wanted a GraphQL server that just worked the second you deployed it without having to write a line of code.
 
-I always liked GraphQL it made everything so simple. Web devs can use GraphQL to fetch exactly the data they need. There is one small issue however you still hasve to write a lot of the same database code.
-
-I wanted a GraphQL server that just worked the second you deployed it without having to write a line of code.
-
-And so after a lot of coffee and some avocado toasts Super Graph was born. An instant GraphQL API service that's high performance and easy to deploy. I hope you find it as useful as I do and there's a lot more coming so hit that :star: to stay in the loop.

-### GraphQL (GQL)
+## Watch some talks
 
-We currently support the `query` action which is used for fetching data. Support for `mutation` and `subscriptions` is work in progress. For example the below GraphQL query would fetch two products that belong to the current user where the price is greater than 10
+[![Watch the video](https://img.youtube.com/vi/TGq9wJAj78I/hqdefault.jpg)](https://youtu.be/TGq9wJAj78I)
 
-#### GQL Query
 
-```gql
-query { 
-  users {
-    id
-    email
-    picture : avatar
-    password
-    full_name
-    products(limit: 2, where: { price: { gt: 10 } }) {
-      id
-      name
-      description
-      price
-    }
-  }
-}
-```
+## Documentation
 
-The above GraphQL query returns the JSON result below. It handles all
-kinds of complexity without you having to writing a line of code. 
-
-For example there is a while greater than `gt` and a limit clause on a child field. And the `avatar` field is renamed to `picture`. The `password` field is blocked and not returned. Finally the relationship between the `users` table and the `products` table is auto discovered and used.
-
-#### JSON Result
-
-```json
-{
-  "data": {
-    "users": [
-      {
-        "id": 1,
-        "email": "odilia@west.info",
-        "picture": "https://robohash.org/simur.png?size=300x300",
-        "full_name": "Edwin Orn",
-        "products": [
-          {
-            "id": 16,
-            "name": "Sierra Nevada Style Ale",
-            "description": "Belgian Abbey, 92 IBU, 4.7%, 17.4°Blg",
-            "price": 16.47
-          },
-          ...
-        ]
-      }
-    ]
-  }
-}
-```
-
-## Try it out
-
-```console
-$ docker-compose run web rake db:create db:migrate db:seed
-$ docker-compose -f docker-compose.image.yml up
-$ open http://localhost:8080
-```
-
-The above command will download the latest docker image for Super Graph and use it to run an example that includes a Postgres DB and a simple Rails ecommerce store app. 
-
-If you want to build and run Super Graph from code then the below commands will build the web ui and launch Super Graph in developer mode with a watcher to rebuild on code changes.
-
-```console
-$ brew install yarn
-$ (cd web && yarn install && yarn build)
-$ go generate ./...
-$ docker-compose up
-```
-
-#### Try with an authenticated user
-
-In development mode you can use the `X-User-ID: 4` header to set a user id so you don't have to worries about cookies etc. This can be set using the *HTTP Headers* tab at the bottom of the web UI you'll see when you visit the above link. You can also directly run queries from the commandline like below.
-
-#### Querying the GQL endpoint
-
-```console
-curl 'http://localhost:8080/api/v1/graphql' \
-  -H 'content-type: application/json' \
-  -H 'X-User-ID: 5' \
-  --data-binary '{"query":"{ products { name price users { email }}}"}'
-```
-
-## How to GraphQL
-
-GraphQL (GQL) is a simple query syntax that's fast replacing REST APIs. GQL is great since it allows web developers to fetch the exact data that they need without depending on changes to backend code. Also if you squint hard enough it looks a little bit like JSON :smiley:
-
-The below query will fetch an `users` name, email and avatar image (renamed as picture). If you also need the users `id` then just add it to the query.
-
-```gql
-query {
-  user {
-    full_name
-    email
-    picture : avatar
-  }
-}
-```
-
-Super Graph support complex queries where you can add filters, ordering,offsets and limits on the query.
-
-#### Logical Operators
-
-Name | Example | Explained |
---- | --- | --- |
-and | price : { and : { gt: 10.5, lt: 20 } | price > 10.5 AND price < 20
-or |  or : { price : { greater_than : 20 }, quantity: { gt : 0 } }  | price >= 20 OR quantity > 0
-not | not: { or : { quantity : { eq: 0 }, price : { eq: 0 } } } | NOT (quantity = 0 OR price = 0)
-
-#### Other conditions
-
-Name | Example | Explained |
---- | --- | --- |
-eq, equals | id : { eq: 100 } | id = 100 
-neq, not_equals | id: { not_equals: 100 } | id != 100
-gt, greater_than | id: { gt: 100 } | id > 100
-lt, lesser_than | id: { gt: 100 } | id < 100
-gte, greater_or_equals | id: { gte: 100 } | id >= 100
-lte, lesser_or_equals | id: { lesser_or_equals: 100 } | id <= 100
-in | status: { in: [ "A", "B", "C" ] } | status IN ('A', 'B', 'C)
-nin, not_in | status: { in: [ "A", "B", "C" ] } | status IN ('A', 'B', 'C)
-like | name: { like "phil%" } | Names starting with 'phil'
-nlike, not_like | name: { nlike "v%m" } | Not names starting with 'v' and ending with 'm'
-ilike | name: { ilike "%wOn" } | Names ending with 'won' case-insensitive
-nilike, not_ilike | name: { nilike "%wOn" } | Not names ending with 'won' case-insensitive
-similar | name: { similar: "%(b\|d)%" } | [Similar Docs](https://www.postgresql.org/docs/9/functions-matching.html#FUNCTIONS-SIMILARTO-REGEXP)
-nsimilar, not_similar | name: { nsimilar: "%(b\|d)%" } | [Not Similar Docs](https://www.postgresql.org/docs/9/functions-matching.html#FUNCTIONS-SIMILARTO-REGEXP)
-has_key | column: { has_key: 'b' } | Does JSON column contain this key
-has_key_any | column: { has_key_any: [ a, b ] } | Does JSON column contain any of these keys
-has_key_all | column: [ a, b ] | Does JSON column contain all of this keys
-contains | column: { contains: [1, 2, 4] } | Is this array/json column a subset of value
-contained_in | column: { contains: "{'a':1, 'b':2}" } | Is this array/json column a subset of these value
-is_null | column: { is_null: true } | Is column value null or not
-
-#### Aggregation
-
-You will often find the need to fetch aggregated values from the database such as `count`, `max`, `min`, etc. This is simple to do with GraphQL, just prefix the aggregation name to the field name that you want to aggregrate like `count_id`. The below query will group products by name and find the minimum price for each group. Notice the `min_price` field we're adding `min_` to price.
-
-```gql
-query {
-  products {
-    name
-    min_price
-  }
-}
-```
-
-Name | Explained |
---- | --- |
-avg | Average value
-count | Count the values
-max | Maximum value
-min | Minimum  value
-stddev | [Standard Deviation](https://en.wikipedia.org/wiki/Standard_deviation)
-stddev_pop | Population Standard Deviation
-stddev_samp | Sample Standard Deviation
-variance | [Variance](https://en.wikipedia.org/wiki/Variance)
-var_pop | Population Standard Variance
-var_samp | Sample Standard variance
-
-All kinds of queries are possible with GraphQL. Below is an example that uses a lot of the features available. Comments `# hello` are also valid within queries.
-
-```javascript
-query {
-  products(
-    # returns only 30 items
-    limit: 30,
-
-    # starts from item 10, commented out for now
-    # offset: 10,
-
-    # orders the response items by highest price
-    order_by: { price: desc },
-
-    # no duplicate prices returned
-    distinct: [ price ]
-    
-    # only items with an id >= 30 and < 30 are returned
-    where: { id: { and: { greater_or_equals: 20, lt: 28 } } }) {
-    id
-    name
-    price
-  }
-}
-```
-
-## It's easy to setup
-
-Configuration files can either be in YAML or JSON their names are derived from the `GO_ENV` variable, for example `GO_ENV=prod` will cause the `prod.yaml` config file to be used. or `GO_ENV=dev` will use the `dev.yaml`. A path to look for the config files in can be specified using the `-path <folder>` command line argument.
-
-```yaml
-host_port: 0.0.0.0:8080
-web_ui: true
-debug_level: 1
-enable_tracing: true

-
-If deploying into environments like Kubernetes it's useful to be able to configure things like secrets and hosts though environment variables therfore we expose the below environment variables. This is escpecially useful for secrets since they are usually injected in via a secrets management framework ie. Kubernetes Secrets
-
-#### Postgres related environment Variables
-```console
-SG_DATABASE_HOST
-SG_DATABASE_PORT
-SG_DATABASE_USER
-SG_DATABASE_PASSWORD
-```
-
-#### Auth related environment Variables
-```console
-SG_AUTH_SECRET_KEY_BASE
-SG_AUTH_PUBLIC_KEY_FILE
-SG_AUTH_URL
-SG_AUTH_PASSWORD
-```
-
-## Authentication
-
-You can only have one type of auth enabled. You can either pick Rails or JWT. Uncomment the one you use and leave the rest commented out.
-
-#### JWT Tokens
-
-```yaml
-auth:
-  type: jwt
-  provider: auth0 #none
-  cookie: _app_session
-  secret: abc335bfcfdb04e50db5bb0a4d67ab9
-  public_key_file: /secrets/public_key.pem
-  public_key_type: ecdsa #rsa
-```
-
-For JWT tokens we currently support tokens from a provider like Auth0
-or if you have a custom solution then we look for the `user_id` in the
-`subject` claim of of the `id token`. If you pick Auth0 then we derive two variables from the token `user_id` and `user_id_provider` for to use in your filters.
-
-We can get the JWT token either from the `authorization` header where we expect it to be a `bearer` token or if `cookie` is specified then we look there.
-
-For validation a `secret` or a public key (ecdsa or rsa) is required. When using public keys they have to be in a PEM format file.
-
-## Deploying Super Graph
-
-How do I deploy the Super Graph service with my existing rails app? You have several options here. Esentially you need to ensure your app's session cookie will be passed to this service. 
-
-#### Custom Docker Image
-
-Create a `Dockerfile` like the one below to roll your own
-custom Super Graph docker image. And to build it `docker build -t my-super-graph .`
-
-```dockerfile
-FROM dosco/super-graph:latest
-WORKDIR /app
-COPY *.yml ./
-```
-
-#### Deploy under a subdomain
-For this to work you have to ensure that the option `:domain => :all` is added to your rails app config `Application.config.session_store` this will cause your rails app to create session cookies that can be shared with sub-domains. More info here <http://excid3.com/blog/sharing-a-devise-user-session-across-subdomains-with-rails-3/>
-
-#### With an NGINX loadbalancer
-I'm sure you know how to configure it so that the Super Graph endpoint path `/api/v1/graphql` is routed to wherever you have this service installed within your architecture.
-
-#### On Kubernetes
-If your Rails app runs on Kubernetes then ensure you have an ingress config deployed that points the path to the service that you have deployed Super Graph under.
-
-#### We use JWT tokens like those from Auth0
-In that case deploy under a subdomain and configure this service to use JWT authentication. You will need the public key file or secret key. Ensure your web app passes the JWT token with every GQL request in the Authorize header as a `bearer` token.

+
+## Why Super Graph?
+
+After working on several product though my career I found building CRUD APIs (Create, Update, Delete, List, Show) to be a big part of the job. It was always the same thing figure out what the UI needs then build an endpoint for it, if related data is needed than join with another table. I didn't want to write that code anymore I wanted the computer to just do it.
+
+I always liked GraphQL it sounded friendly, but it still required me to write all the same database query code. Sure the API was nicer but it took a lot of work sometime even more than a simple REST API would have. I wanted a GraphQL server that just worked the second you deployed it without having to write a line of code.
+
+And so after a lot of coffee and some Avocado toasts __Super Graph was born, a GraphQL server that just works, is high performance and easy to deploy__. I hope you find it as useful as I do and there's a lot more coming so hit that :star: to stay in the loop.

+
+## How to deploy Super Graph
+
+Since you're reading this you're probably considering deploying Super Graph. You're in luck it's really easy and there are several ways to choose from. Keep in mind Super Graph can be used as a pre-built docker image or you can easily customize it and build your own docker image.
+
+### Alongside an existing Rails app
+
+Super Graph can read Rails session cookies, like those created by authentication gems (Devise or Warden). Based on how you've configured your Rails app the cookie can be signed, encrypted, both, include the user ID or just have the ID of the session. If you have choosen to use Redis or Memcache as your session store then Super Graph can read the session cookie and then lookup the user in the session store. In short it works really well with almost all Rails apps.
+
+For any of this to work Super Graph must be deployed in a way that make the browser send the apps cookie to it along with the GraphQL query. That means Super Graph needs to be either on the same domain as your app or on a subdomain.
+
+::: tip I need an example
+Say your Rails app runs on `myrailsapp.com` then Super Graph should be on the same domain or on a subdomain like `graphql.myrailsapp.com`. If you choose subdomain then remeber read the [Deploy under a subdomain](#deploy-under-a-subdomain) section.
+:::
+
+### Custom Docker Image
+
+You might find the need to customize the Super Graph config file to fit your app and then package it into a docker image. This is easy to do below is an example `Dockerfile` to do exactly this. And to build it `docker build -t my-super-graph .`
+
+```docker
+FROM dosco/super-graph:latest
+WORKDIR /app
+COPY *.yml ./
+```
+
+### Deploy under a subdomain
+
+For this to work you have to ensure that the option `:domain => :all` is added to your Rails app config `Application.config.session_store` this will cause your rails app to create session cookies that can be shared with sub-domains. More info here [/sharing-a-devise-user-session-across-subdomains-with-rails](http://excid3.com/blog/sharing-a-devise-user-session-across-subdomains-with-rails-3/)
+
+### With an NGINX loadbalancer
+
+If you're infrastructure is fronted by NGINX then it should be configured so that all requests to your GraphQL API path are proxyed to Super Graph. In the example NGINX config below all requests to the path `/api/v1/graphql` are routed to wherever you have Super Graph installed within your architecture. This example is derived from the config file example at [/microservices-nginx-gateway/nginx.conf](https://github.com/launchany/microservices-nginx-gateway/blob/master/nginx.conf)
+
+::: tip NGINX with sub-domain
+Yes, NGINX is very flexible and you can configure it to keep Super Graph a subdomain instead of on the same top level domain. I'm sure a little Googleing will get you some great example configs for that.
+:::
+
+```nginx
+# Configuration for the server
+server {
+
+	# Running port
+	listen 80;
+
+	# Proxy the graphql api path to Super Graph
+	location /api/v1/graphql {
+
+			proxy_pass         http://super-graph-service:8080;
+			proxy_redirect     off;
+			proxy_set_header   Host $host;
+			proxy_set_header   X-Real-IP $remote_addr;
+			proxy_set_header   X-Forwarded-For $proxy_add_x_forwarded_for;
+			proxy_set_header   X-Forwarded-Host $server_name;
+
+	}
+
+	# Proxying all other paths to your Rails app
+	location / {
+
+			proxy_pass         http://your-rails-app:3000;
+			proxy_redirect     off;
+			proxy_set_header   Host $host;
+			proxy_set_header   X-Real-IP $remote_addr;
+			proxy_set_header   X-Forwarded-For $proxy_add_x_forwarded_for;
+			proxy_set_header   X-Forwarded-Host $server_name;
+
+	}
+}
+```
+
+### On Kubernetes
+
+If your Rails app runs on Kubernetes then ensure you have an ingress config deployed that points the path to the service that you have deployed Super Graph under.
+
+#### Ingress config
+
+```yaml
+apiVersion: extensions/v1beta1
+kind: Ingress
+metadata:
+  name: simple-rails-app
+  annotations:
+    nginx.ingress.kubernetes.io/rewrite-target: /
+spec:
+  rules:
+  - host: myrailsapp.com
+    http:
+      paths:
+      - path: /api/v1/graphql
+        backend:
+          serviceName: graphql-service
+          servicePort: 8080
+      - path: /
+        backend:
+          serviceName: rails-app
+          servicePort: 3000
+```
+
+#### Service and deployment config
+
+```yaml
+apiVersion: v1
+kind: Service
+metadata:
+  name: graphql-service
+  labels:
+    run: super-graph
+spec:
+  ports:
+  - port: 8080
+    protocol: TCP
+  selector:
+    run: super-graph
+
+---
+
+apiVersion: apps/v1
+kind: Deployment
+metadata:
+  name: super-graph
+spec:
+  selector:
+    matchLabels:
+      run: super-graph
+  replicas: 2
+  template:
+    metadata:
+      labels:
+        run: super-graph
+    spec:
+      containers:
+      - name: super-graph
+        image: docker.io/dosco/super-graph:latest
+        ports:
+        - containerPort: 8080
+```
+
+### JWT tokens (Auth0, etc)
+
+In that case deploy under a subdomain and configure this service to use JWT authentication. You will need the public key file or secret key. Ensure your web app passes the JWT token with every GQL request in the Authorize header as a `bearer` token.

+## Try it out
+
+```bash
+# download super graph source
+git clone https://github.com/dosco/super-graph.git
+
+# setup the demo rails app & database and run it
+./demo start
+
+# signin to the demo app (user1@demo.com / 123456)
+open http://localhost:3000
+
+# try the super graph web ui
+open http://localhost:8080
+```
+
+::: warning DEMO REQUIREMENTS
+This demo requires `docker` you can either install it using `brew` or from the
+docker website [https://docs.docker.com/docker-for-mac/install/](https://docs.docker.com/docker-for-mac/install/)
+:::
+
+#### Trying out GraphQL
+
+We currently support the `query` action which is used for fetching data. Support for `mutation` and `subscriptions` is work in progress. For example the below GraphQL query would fetch two products that belong to the current user where the price is greater than 10
+
+#### GQL Query
+
+```graphql
+query {
+  users {
+    id
+    email
+    picture : avatar
+    password
+    full_name
+    products(limit: 2, where: { price: { gt: 10 } }) {
+      id
+      name
+      description
+      price
+    }
+  }
+}
+```
+
+The above GraphQL query returns the JSON result below. It handles all
+kinds of complexity without you having to writing a line of code.
+
+For example there is a while greater than `gt` and a limit clause on a child field. And the `avatar` field is renamed to `picture`. The `password` field is blocked and not returned. Finally the relationship between the `users` table and the `products` table is auto discovered and used.
+
+#### JSON Result
+
+```json
+{
+  "data": {
+    "users": [
+      {
+        "id": 1,
+        "email": "odilia@west.info",
+        "picture": "https://robohash.org/simur.png?size=300x300",
+        "full_name": "Edwin Orn",
+        "products": [
+          {
+            "id": 16,
+            "name": "Sierra Nevada Style Ale",
+            "description": "Belgian Abbey, 92 IBU, 4.7%, 17.4°Blg",
+            "price": 16.47
+          },
+          ...
+        ]
+      }
+    ]
+  }
+}
+```
+
+#### Try with an authenticated user
+
+In development mode you can use the `X-User-ID: 4` header to set a user id so you don't have to worries about cookies etc. This can be set using the *HTTP Headers* tab at the bottom of the web UI you'll see when you visit the above link. You can also directly run queries from the commandline like below.
+
+#### Querying the GQL endpoint
+
+```bash
+
+# fetch the response json directly from the endpoint using user id 5
+curl 'http://localhost:8080/api/v1/graphql' \
+  -H 'content-type: application/json' \
+  -H 'X-User-ID: 5' \
+  --data-binary '{"query":"{ products { name price users { email }}}"}'
+
+```
+
+## How to GraphQL
+
+GraphQL (GQL) is a simple query syntax that's fast replacing REST APIs. GQL is great since it allows web developers to fetch the exact data that they need without depending on changes to backend code. Also if you squint hard enough it looks a little bit like JSON :smiley:
+
+The below query will fetch an `users` name, email and avatar image (renamed as picture). If you also need the users `id` then just add it to the query.
+
+```graphql
+query {
+  user {
+    full_name
+    email
+    picture : avatar
+  }
+}
+```
+
+### Fetching data
+
+To fetch a specific `product` by it's ID you can use the `id` argument. The real name id field will be resolved automatically so this query will work even if your id column is named something like `product_id`.
+
+```graphql
+query {
+  products(id: 3) {
+    name
+  }
+}
+```
+
+Postgres also supports full text search using a TSV index. Super Graph makes it easy to use this full text search capability using the `search` argument.
+
+```graphql
+query {
+  products(search: "ale") {
+    name
+  }
+}
+```
+
+### Complex queries (Where)
+
+Super Graph support complex queries where you can add filters, ordering,offsets and limits on the query.
+
+#### Logical Operators
+
+Name | Example | Explained |
+--- | --- | --- |
+and | price : { and : { gt: 10.5, lt: 20 } | price > 10.5 AND price < 20
+or |  or : { price : { greater_than : 20 }, quantity: { gt : 0 } }  | price >= 20 OR quantity > 0
+not | not: { or : { quantity : { eq: 0 }, price : { eq: 0 } } } | NOT (quantity = 0 OR price = 0)
+
+#### Other conditions
+
+Name | Example | Explained |
+--- | --- | --- |
+eq, equals | id : { eq: 100 } | id = 100
+neq, not_equals | id: { not_equals: 100 } | id != 100
+gt, greater_than | id: { gt: 100 } | id > 100
+lt, lesser_than | id: { gt: 100 } | id < 100
+gte, greater_or_equals | id: { gte: 100 } | id >= 100
+lte, lesser_or_equals | id: { lesser_or_equals: 100 } | id <= 100
+in | status: { in: [ "A", "B", "C" ] } | status IN ('A', 'B', 'C)
+nin, not_in | status: { in: [ "A", "B", "C" ] } | status IN ('A', 'B', 'C)
+like | name: { like "phil%" } | Names starting with 'phil'
+nlike, not_like | name: { nlike "v%m" } | Not names starting with 'v' and ending with 'm'
+ilike | name: { ilike "%wOn" } | Names ending with 'won' case-insensitive
+nilike, not_ilike | name: { nilike "%wOn" } | Not names ending with 'won' case-insensitive
+similar | name: { similar: "%(b\|d)%" } | [Similar Docs](https://www.postgresql.org/docs/9/functions-matching.html#FUNCTIONS-SIMILARTO-REGEXP)
+nsimilar, not_similar | name: { nsimilar: "%(b\|d)%" } | [Not Similar Docs](https://www.postgresql.org/docs/9/functions-matching.html#FUNCTIONS-SIMILARTO-REGEXP)
+has_key | column: { has_key: 'b' } | Does JSON column contain this key
+has_key_any | column: { has_key_any: [ a, b ] } | Does JSON column contain any of these keys
+has_key_all | column: [ a, b ] | Does JSON column contain all of this keys
+contains | column: { contains: [1, 2, 4] } | Is this array/json column a subset of value
+contained_in | column: { contains: "{'a':1, 'b':2}" } | Is this array/json column a subset of these value
+is_null | column: { is_null: true } | Is column value null or not
+
+### Aggregation (Max, Count, etc)
+
+You will often find the need to fetch aggregated values from the database such as `count`, `max`, `min`, etc. This is simple to do with GraphQL, just prefix the aggregation name to the field name that you want to aggregrate like `count_id`. The below query will group products by name and find the minimum price for each group. Notice the `min_price` field we're adding `min_` to price.
+
+```graphql
+query {
+  products {
+    name
+    min_price
+  }
+}
+```
+
+Name | Explained |
+--- | --- |
+avg | Average value
+count | Count the values
+max | Maximum value
+min | Minimum  value
+stddev | [Standard Deviation](https://en.wikipedia.org/wiki/Standard_deviation)
+stddev_pop | Population Standard Deviation
+stddev_samp | Sample Standard Deviation
+variance | [Variance](https://en.wikipedia.org/wiki/Variance)
+var_pop | Population Standard Variance
+var_samp | Sample Standard variance
+
+All kinds of queries are possible with GraphQL. Below is an example that uses a lot of the features available. Comments `# hello` are also valid within queries.
+
+```graphql
+query {
+  products(
+    # returns only 30 items
+    limit: 30,
+
+    # starts from item 10, commented out for now
+    # offset: 10,
+
+    # orders the response items by highest price
+    order_by: { price: desc },
+
+    # no duplicate prices returned
+    distinct: [ price ]
+
+    # only items with an id >= 30 and < 30 are returned
+    where: { id: { and: { greater_or_equals: 20, lt: 28 } } }) {
+    id
+    name
+    price
+  }
+}
+```
+
+### Using variables
+
+Variables (`$product_id`) and their values (`"product_id": 5`) can be passed along side the GraphQL query. Using variables makes for better client side code as well as improved server side SQL query caching. The build-in web-ui also supports setting variables. Not having to manipulate your GraphQL query string to insert values into it makes for cleaner
+and better client side code.
+
+```javascript
+// Define the request object keeping the query and the variables seperate
+var req = { 
+  query: '{ product(id: $product_id) { name } }' ,
+  variables: { "product_id": 5 }
+}
+
+// Use the fetch api to make the query
+fetch('http://localhost:8080/api/v1/graphql', {
+  method: 'POST',
+  headers: { 'Content-Type': 'application/json' },
+  body: JSON.stringify(req),
+})
+.then(res => res.json())
+.then(res => console.log(res.data));
+```
+
+### Full text search
+
+Every app these days needs search. Enought his often means reaching for something heavy like Solr. While this will work why add complexity to your infrastructure when Postgres has really great
+and fast full text search built-in. And since it's part of Postgres it's also available in Super Graph.
+
+```graphql
+query {
+  products(
+    # Search for all products that contain 'ale' or some version of it
+    search: "ale"
+
+    # Return only matches where the price is less than 10
+    where: { price: { lt: 10 } }
+
+    # Use the search_rank to order from the best match to the worst
+    order_by: { search_rank: desc }) {
+    id
+    name
+    search_rank
+   	search_headline_description
+  }
+}
+```
+
+This query will use the `tsvector` column in your database table to search for products that contain the query phrase or some version of it. To get the internal relevance ranking for the search results using the `search_rank` field. And to get the highlighted context within any of the table columns you can use the `search_headline_` field prefix. For example `search_headline_name` will return the contents of the products name column which contains the matching query marked with the `<b></b>` html tags.
+
+```json
+{
+  "data": {
+    "products": [
+      {
+        "id": 11,
+        "name": "Maharaj",
+        "search_rank": 0.243171,
+        "search_headline_description": "Blue Moon, Vegetable Beer, Willamette, 1007 - German <b>Ale</b>, 48 IBU, 7.9%, 11.8°Blg"
+      },
+      {
+        "id": 12,
+        "name": "Schneider Aventinus",
+        "search_rank": 0.243171,
+        "search_headline_description": "Dos Equis, Wood-aged Beer, Magnum, 1099 - Whitbread <b>Ale</b>, 15 IBU, 9.5%, 13.0°Blg"
+      },
+  ...
+```
+
+#### Adding search to your Rails app
+
+It's really easy to enable Postgres search on any table within your database schema. All it takes is to create the following migration. In the below example we add a full-text search to the `products` table.
+
+```ruby
+class AddSearchColumn < ActiveRecord::Migration[5.1]
+  def self.up
+    add_column :products, :tsv, :tsvector
+    add_index :products, :tsv, using: "gin"
+
+    say_with_time("Adding trigger to update the ts_vector column") do
+      execute <<-SQL
+        CREATE FUNCTION products_tsv_trigger() RETURNS trigger AS $$
+        begin
+          new.tsv :=
+          setweight(to_tsvector('pg_catalog.english', coalesce(new.name,'')), 'A') ||
+          setweight(to_tsvector('pg_catalog.english', coalesce(new.description,'')), 'B');
+          return new;
+        end
+        $$ LANGUAGE plpgsql;
+
+        CREATE TRIGGER tsvectorupdate BEFORE INSERT OR UPDATE ON products FOR EACH ROW EXECUTE PROCEDURE products_tsv_trigger();
+        SQL
+      end
+  end
+
+  def self.down
+    say_with_time("Removing trigger to update the tsv column") do
+      execute <<-SQL
+        DROP TRIGGER tsvectorupdate
+        ON products
+        SQL
+    end
+
+    remove_index :products, :tsv
+    remove_column :products, :tsv
+  end
+end
+```
+
+## Remote Joins
+
+It often happens that after fetching some data from the DB we need to call another API to fetch some more data and all this combined into a single JSON response. For example along with a list of users you need their last 5 payments from Stripe. This requires you to query your DB for the users and Stripe for the payments. Super Graph handles all this for you also only the fields you requested from the Stripe API are returned. 
+
+::: tip Is this fast?
+Super Graph is able fetch remote data and merge it with the DB response in an efficient manner. Several optimizations such as parallel HTTP requests and a zero-allocation JSON merge algorithm makes this very fast. All of this without you having to write a line of code.
+:::
+
+For example you need to list the last 3 payments made by a user. You will first need to look up the user in the database and then call the Stripe API to fetch his last 3 payments. For this to work your user table in the db has a `customer_id` column that contains his Stripe customer ID.
+
+Similiarly you could also fetch the users last tweet, lead info from Salesforce or whatever else you need. It's fine to mix up several different `remote joins` into a single GraphQL query.
+
+### Stripe API example
+
+The configuration is self explanatory. A `payments` field has been added under the `customers` table. This field is added to the `remotes` subsection that defines fields associated with `customers` that are remote and not real database columns.
+
+The `id` parameter maps a column from the `customers` table to the `$id` variable. In this case it maps `$id` to the `customer_id` column.
+
+```yaml
+tables:
+  - name: customers
+    remotes:
+      - name: payments
+        id: stripe_id
+        url: http://rails_app:3000/stripe/$id
+        path: data
+        # debug: true
+        # pass_headers: 
+        #   - cookie
+        #   - host
+        set_headers:
+          - name: Authorization
+            value: Bearer <stripe_api_key>
+```
+
+#### How do I make use of this?
+
+Just include `payments` like you would any other GraphQL selector under the `customers` selector. Super Graph will call the configured API for you and stitch (merge) the JSON the API sends back with the JSON generated from the database query. GraphQL features like aliases and fields all work.
+
+```graphql
+query {
+  customers {
+    id
+    email
+    payments {
+      customer_id
+      amount
+      billing_details
+    }
+  }
+}
+```
+
+And voila here is the result. You get all of this advanced and honestly complex querying capability without writing a single line of code.
+
+```json
+"data": {
+  "customers": [
+    {
+      "id": 1,
+      "email": "linseymertz@reilly.co",
+      "payments": [
+        {
+          "customer_id": "cus_YCj3ndB5Mz",
+          "amount": 100,
+            "billing_details": {
+            "address": "1 Infinity Drive",
+            "zipcode": "94024"
+          }
+        },
+      ...
+```
+
+Even tracing data is availble in the Super Graph web UI if tracing is enabled in the config. By default it is enabled in development. Additionally there you can set `debug: true` to enable http request / response dumping to help with debugging.

+
+## Authentication
+
+You can only have one type of auth enabled. You can either pick Rails or JWT. 
+
+### Rails Auth (Devise / Warden)
+
+Almost all Rails apps use Devise or Warden for authentication. Once the user is
+authenticated a session is created with the users ID. The session can either be
+stored in the users browser as a cookie, memcache or redis. If memcache or redis is used then a cookie is set in the users browser with just the session id.
+
+Super Graph can handle all these variations including the old and new session formats. Just enable the right `auth` config based on how your rails app is configured.
+
+#### Cookie session store
+
+```yaml
+auth:
+  type: rails
+  cookie: _app_session
+
+  rails:
+    # Rails version this is used for reading the
+    # various cookies formats.
+    version: 5.2
+
+    # Found in 'Rails.application.config.secret_key_base'
+    secret_key_base: 0a248500a64c01184edb4d7ad3a805488f8097ac761b76aaa6c17c01dcb7af03a2f18ba61b2868134b9c7b79a122bc0dadff4367414a2d173297bfea92be5566
+
+```
+
+#### Memcache session store
+
+```yaml
+auth:
+  type: rails
+  cookie: _app_session
+
+  rails:
+    # Memcache remote cookie store.
+    url: memcache://127.0.0.1
+```
+
+#### Redis session store
+
+```yaml
+auth:
+  type: rails
+  cookie: _app_session
+
+  rails:
+    # Redis remote cookie store
+    url: redis://127.0.0.1:6379
+    password: ""
+    max_idle: 80
+    max_active: 12000
+```
+
+### JWT Token Auth
+
+```yaml
+auth:
+  type: jwt
+
+  jwt:
+    # the two providers are 'auth0' and 'none'
+    provider: auth0 
+    secret: abc335bfcfdb04e50db5bb0a4d67ab9
+    public_key_file: /secrets/public_key.pem
+    public_key_type: ecdsa #rsa
+```
+
+For JWT tokens we currently support tokens from a provider like Auth0
+or if you have a custom solution then we look for the `user_id` in the
+`subject` claim of of the `id token`. If you pick Auth0 then we derive two variables from the token `user_id` and `user_id_provider` for to use in your filters.
+
+We can get the JWT token either from the `authorization` header where we expect it to be a `bearer` token or if `cookie` is specified then we look there.
+
+For validation a `secret` or a public key (ecdsa or rsa) is required. When using public keys they have to be in a PEM format file.
+
+## Easy to setup
+
+Configuration files can either be in YAML or JSON their names are derived from the `GO_ENV` variable, for example `GO_ENV=prod` will cause the `prod.yaml` config file to be used. or `GO_ENV=dev` will use the `dev.yaml`. A path to look for the config files in can be specified using the `-path <folder>` command line argument.
+
+We're tried to ensure that the config file is self documenting and easy to work with.
+
+```yaml
+app_name: "Super Graph Development"
+host_port: 0.0.0.0:8080
+web_ui: true
+debug_level: 1
+
+# debug, info, warn, error, fatal, panic, disable

+```
+
+If deploying into environments like Kubernetes it's useful to be able to configure things like secrets and hosts though environment variables therfore we expose the below environment variables. This is escpecially useful for secrets since they are usually injected in via a secrets management framework ie. Kubernetes Secrets
+
+Keep in mind any value can be overwritten using environment variables for example `auth.jwt.public_key_type` converts to `SG_AUTH_JWT_PUBLIC_KEY_TYPE`. In short prefix `SG_`, upper case and all `.` should changed to `_`.
+
+#### Postgres environment variables
+```bash
+SG_DATABASE_HOST
+SG_DATABASE_PORT
+SG_DATABASE_USER
+SG_DATABASE_PASSWORD
+```
+
+#### Auth environment variables
+```bash
+SG_AUTH_RAILS_COOKIE_SECRET_KEY_BASE
+SG_AUTH_RAILS_REDIS_URL
+SG_AUTH_RAILS_REDIS_PASSWORD
+SG_AUTH_JWT_PUBLIC_KEY_FILE
+```
+
+## Developing Super Graph
+
+If you want to build and run Super Graph from code then the below commands will build the web ui and launch Super Graph in developer mode with a watcher to rebuild on code changes. And the demo rails app is also launched to make it essier to test changes.
+
+```bash
+
+# yarn is needed to build the web ui
+brew install yarn
+
+# yarn install dependencies and build the web ui
+(cd web && yarn install && yarn build)
+
+# generate some stuff the go code needs
+go generate ./...
+
+# do this the only the time to setup the database
+docker-compose run rails_app rake db:create db:migrate db:seed
+
+# start super graph in development mode with a change watcher
+docker-compose up
+
+```

+# JSN - Fast low allocation JSON library
+## Design
+
+This libary is designed as a set of seperate functions to extract data and mutate
+JSON. All functions are focused on keeping allocations to a minimum and be as fast
+as possible. The functions don't validate the JSON a seperate `Validate` function
+does that. 
+
+The JSON parsing algo processes each object `{}` or array `[]` in a bottom up way
+where once the end of the array or object is found only then the keys within it are 
+parsed from the top down.

+## Functions
+
+- Strip: Strip a path from the root to a child node and return the rest
+- Replace: Replace values by key
+- Get: Get all keys
+- Filter: Extract specific keys from an object
+- Tree: Fetch unique keys from an array or object
