+```console

+super-graph new <app_name>
+```
 
-Is designed to 100x your developer productivity. Super Graph will instantly and without you writing code provide you a high performance and secure GraphQL API for Postgres DB. GraphQL queries are translated into a single fast SQL query. No more writing API code as you develop 
+## Using it in your own code
-your web frontend just make the query you need and Super Graph will do the rest.
 
-Super Graph has a rich feature set like integrating with your existing Ruby on Rails apps, joining your DB with data from remote APIs, role and attribute based access control, support for JWT tokens, built-in DB mutations and seeding, and a lot more.

+## About Super Graph
+
+After working on several products through my career I found that we spend way too much time on building API backends. Most APIs also need constant updating, and this costs time and money.
 
-After working on several products through my career I find that we spend way too much time on building API backends. Most APIs also require constant updating, this costs real time and money.
-            
 It's always the same thing, figure out what the UI needs then build an endpoint for it. Most API code involves struggling with an ORM to query a database and mangle the data into a shape that the UI expects to see.
 
 I didn't want to write this code anymore, I wanted the computer to do it. Enter GraphQL, to me it sounded great, but it still required me to write all the same database query code.
 
 Having worked with compilers before I saw this as a compiler problem. Why not build a compiler that converts GraphQL to highly efficient SQL.
 
-This compiler is what sits at the heart of Super Graph with layers of useful functionality around it like authentication, remote joins, rails integration, database migrations and everything else needed for you to build production ready apps with it.

-            Super Graph can automatically learn a Postgres database and instantly serve it as a fast and secured GraphQL API. It comes with tools to create a new app and manage it's database. You get it all, a very productive developer and a highly scalable app backend. It's designed to work well on serverless platforms by Google, AWS, Microsoft, etc. The goal is to save you a ton of time and money so you can focus on you're apps core value.

-          <div class="text-2xl md:text-3xl">
-            After working on several products through my career I find that we spend way too much time on building API backends. Most APIs also require constant updating, this costs real time and money.<br><br>
-            
-            It's always the same thing, figure out what the UI needs then build an endpoint for it. Most API code involves struggling with an ORM to query a database and mangle the data into a shape that the UI expects to see.<br><br>
-            
-            I didn't want to write this code anymore, I wanted the computer to do it. Enter GraphQL, to me it sounded great, but it still required me to write all the same database query code.<br><br>
-            
-            Having worked with compilers before I saw this as a compiler problem. Why not build a compiler that converts GraphQL to highly efficient SQL.<br><br>
-            
-            This compiler is what sits at the heart of Super Graph with layers of useful functionality around it like authentication, remote joins, rails integration, database migrations and everything else needed for you to build production ready apps with it.

+          After working on several products through my career I find that we spend way too much time on building API backends. Most APIs also require constant updating, this costs real time and money.<br><br>
+          
+          It's always the same thing, figure out what the UI needs then build an endpoint for it. Most API code involves struggling with an ORM to query a database and mangle the data into a shape that the UI expects to see.<br><br>
+          
+          I didn't want to write this code anymore, I wanted the computer to do it. Enter GraphQL, to me it sounded great, but it still required me to write all the same database query code.<br><br>
+          
+          Having worked with compilers before I saw this as a compiler problem. Why not build a compiler that converts GraphQL to highly efficient SQL.<br><br>
+          
+          This compiler is what sits at the heart of Super Graph with layers of useful functionality around it like authentication, remote joins, rails integration, database migrations and everything else needed for you to build production ready apps with it.
