+fuel-web
+========
 
-This is the main repository with ISO build scripts.
-It has links to two submodules:
-- Astute, which is deployment orchestrator
-- Fuel Library, which is set of Puppet modules
+fuel-web (nailgun) implements REST API and deployment data
+management. It manages disk volumes configuration data, networks
+configuration data and any other environment specific data which
+are necessary for successful deployment. It has required
+orchestration logic to build instructions for provisioning
+and deployment in a right order. Nailgun uses SQL database
+to store its data and AMQP service to interact with workers.
