+# GitLab4J FORK
+
+This is a fork of https://github.com/gitlab4j/gitlab4j-api intended for quicker releases of contributed features.
+
+This fork should NOT diverge from the original source code, except for support commits, that should be added to the `forks/base` branch.
+
+The sole goal of this fork is to allow features that will be contributed to the source repository to be released earlier than official releases,
+as well as make it easier to test these features.
+
+Once new versions are released, we should create a new branch named `forks/{versionNumber}`, e.g. `forks/6.0.1` based on
+`forks/base` and rebased onto the commit of the released version.
+
+Please always contribute back to the source repository and don't implement or create dependencies on features that are not
+accepted.
