Documentation on using EF7 is available at https://ef.readthedocs.org.
This project is for Entity Framework 7, which is currently in pre-release. Entity Framework 6.x is the latest stable release of EF and still under active development on CodePlex at https://entityframework.codeplex.com/.
Entity Framework 7 (EF7) provides a familiar developer experience to previous versions of EF, including LINQ, POCO, and Code First support. EF7 also enables access to data across relational and non-relational stores. EF7 is much more lightweight than previous versions and is built from the ground up to work great in the cloud (using ASP.NET 5) on devices (i.e. in universal Windows apps) as well as in traditional .NET scenarios.
See the "Getting Started" guides in the EF documentation for tutorials on using EF7.
EF 7 is currently pre-release. For more details on the release schedule, see the Roadmap article in the wiki.
