-## Technical Preview Contents
-
-This technical preview contains a [draft specification for GraphQL]
-(https://github.com/facebook/graphql) and a reference implementation in
-JavaScript that implements that draft, GraphQL.js.
-
-The reference implementation provides base libraries in JavaScript that would
-provide the basis for full GraphQL implementations and tools. It is not a fully
-standalone GraphQL server that a client developer could use to start
-manipulating and querying data. Most importantly, it provides no mapping to a
-functioning, production-ready backend. The only "backend" we have targeted for
-this early preview are in-memory stubs in test cases.
-
-We are releasing this now because after GraphQL was first discussed publicly,
-many engineers used this information to implement the parts of the system that
-we discussed publicly. We want to support those engineers by providing both a
-formal specification and a reference implementation for the system as a whole.
-
-To that end, the target audience is not the client developer, but those who have
-built or are actively interested in building their own GraphQL implementations and
-tools. Critically, we also want feedback on the system and to incorporate that
-feedback in our final release.
-
-In order to be broadly adopted, GraphQL will have to target a wide
-variety of backends, frameworks, and languages, which will necessitate a
-collaborative effort across projects and organizations. This technical preview
-marks the beginning of that process.
