+# Deployment
+
+We know 3 types of release builds:
+- development (beta/dev)
+- staging (rc)
+- productive (stable)
+
+## Versioning
+The format of version is *MAJOR.BUILD*. Everytime we create a new release with same userland, we bump the build number.
+The development use here own major number they will be bump for the stable version and the development version go to next major number.
+
+```
+0.x = development
+1.x = stable
+2.x = development
+3.x = stable
+```
+
+## GIT Branch/Tag
+The branch `dev` ist the actual development branch and from there we never make a release. The `master` branch hould the development
+version from they we build a beta release.
+
+If we create a new staging/productive release, we create a new branch `rel-{MAJOR}`. They will be used for the hole cycle of this release.
