gitlab-workhorse/README.md

+# GitLab-Workhorse in GitLab Development Kit
+
+In GDK, gitlab-workhorse is installed inside its own GOPATH rooted here.
+
+To set GOPATH in your current shell for working on gitlab-workhorse run the following command:
+
+```
+. env.sh
+```
+
+The gitlab-workhorse repository is cloned into:
+
+```
+gitlab-workhorse/src/gitlab.com/gitlab-org/gitlab-workhorse
+```
+
+You can use the following shortcut to `cd` into that directory:
+
+```
+. cd.sh
+```
+
+## Cleaning up an old gitlab-workhorse checkout
+
+If you installed GDK before we started using a GOPATH for gitlab-workhorse you now have a bit of a mess in this directory. You can clean up as follows. Start in the GitLab Development Kit root.
+
+```
+# in GDK root!!
+mv gitlab-workhorse gitlab-workhorse.old.$(date +%s)
+git checkout -- gitlab-workhorse
+make
+```

gitlab-workhorse/cd.sh

+cd src/gitlab.com/gitlab-org/gitlab-workhorse

gitlab-workhorse/env.sh

+export GOPATH=$(pwd)
+echo "GOPATH=$GOPATH"
+export PATH=$(pwd)/bin:$PATH
+echo "PATH=$PATH"
