 ## Road to GraphQL
 
-We have changed our plans to move to GraphQL. After reviewing the GraphQL license, anything related to the Facebook BSD plus patent license will not be allowed at GitLab.
+Going forward, we will start on moving to
+[GraphQL](http://graphql.org/learn/best-practices/) and deprecate the use of
+controller-specific endpoints. GraphQL has a number of benefits:
+
+1. We avoid having to maintain two different APIs.
+2. Callers of the API can request only what they need.
+3. It is versioned by default.
+
+It will co-exist with the current v4 REST API. If we have a v5 API, this should
+be a compatibility layer on top of GraphQL.
+
+Although there were some patenting and licensing concerns with GraphQL, these
+have been resolved to our satisfaction by the relicensing of the reference
+implementations under MIT, and the use of the OWF license for the GraphQL
+specification.
