 What's an Ansible callback ?

 Yes.
 
-The defaults are set to have the callback use the offline API client which
-expects the server dependencies installed and the data is saved to a local
-sqlite database.
+By default ara operates "offline" on localhost, recording Ansible playbook results
+to a local sqlite database without requiring users to start a server.
+
+According to preference or use case, the data can be saved to local (or remote)
+MySQL or PostgreSQL databases instead.
+
+The ara server (based on django & django-rest-framework) provides the reporting
+interface as well as the API used by the ara Ansible plugins.
+
+The server's state is stored in the database and it can be self hosted anywhere.
+Running multiple servers allows for load balancing, scalability and high availability.
 
-However, the callback can also be configured to send data to a specified API
-server address and the API server can be configured to use a remote database
-server such as PostgreSQL or MySQL.
+To make use of a persistent server, configure the ara Ansible plugins with:
 
-The web client interface provided by ara-web_ is stateless and requires an API
-server address to connect to.
-It can be installed anywhere that has access to the API server.
