+## Purpose
+
+The goal of this project is to make the easiest, fastest, and most
+painless way of setting up a self-hosted Git service.
+Using Go, this can be done with an independent binary distribution across
+**all platforms** which Go supports, including Linux, macOS, and Windows
+on x86, amd64, ARM and PowerPC architectures.
+Want to try it before doing anything else?
+Do it [with the online demo](https://try.gitea.io/)!
+This project has been
+[forked](https://blog.gitea.io/2016/12/welcome-to-gitea/) from
+[Gogs](https://gogs.io) since 2016.11 but changed a lot.
+
+## Building
+
+From the root of the source tree, run:
+
+    TAGS="bindata" make build
+
+or if sqlite support is required:
+
+    TAGS="bindata sqlite sqlite_unlock_notify" make build
+
+The `build` target is split into two sub-targets:
+
+- `make backend` which requires [Go 1.12](https://golang.org/dl/) or greater.
+- `make frontend` which requires [Node.js 10.13](https://nodejs.org/en/download/) or greater.
+
+If pre-built frontend files are present it is possible to only build the backend:
+
+		TAGS="bindata" make backend
+

+support with [documentation](https://try.gitea.io/api/swagger).
