@@ -1339,6 +1339,51 @@ We can get the JWT token either from the `authorization` header where we expect
 
 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.
 
+### HTTP Headers
+
+```yaml
+header:
+  name: X-AppEngine-QueueName
+  exists: true
+  #value: default
+```
+
+Header auth is usually the best option to authenticate requests to the action endpoints. For example you
+might want to use an action to refresh a materalized view every hour and only want a cron service like the Google AppEngine Cron service to make that request in this case a config similar to the one above will do. 
+
+The `exists: true` parameter ensures that only the existance of the header is checked not its value. The `value` parameter lets you confirm that the value matches the one assgined to the parameter. This helps in the case you are using a shared secret to protect the endpoint.
+
+### Named Auth
+
+```yaml
+# You can add additional named auths to use with actions
+# In this example actions using this auth can only be
+# called from the Google Appengine Cron service that
+# sets a special header to all it's requests
+auths:
+  - name: from_taskqueue
+    type: header
+    header:
+      name: X-Appengine-Cron
+      exists: true
+```
+
+In addition to the default auth configuration you can create additional named auth configurations to be used
+with features like `actions`. For example while your main GraphQL endpoint uses JWT for authentication you may want to use a header value to ensure your actions can only be called by clients having access to a shared secret
+or security header.
+
+## Actions
+
+Actions is a very useful feature that is currently work in progress. For now the best use case for actions is to
+refresh database tables like materialized views or call a database procedure to refresh a cache table, etc. An action creates an http endpoint that anyone can call to have the SQL query executed. The below example will create an endpoint `/api/v1/actions/refresh_leaderboard_users` any request send to that endpoint will cause the sql query to be executed. the `auth_name` points to a named auth that should be used to secure this endpoint. In future we have big plans to allow your own custom code to run using actions.

+```yaml
+actions:
+  - name: refresh_leaderboard_users
+    sql: REFRESH MATERIALIZED VIEW CONCURRENTLY "leaderboard_users"
