Merge remote-tracking branch 'pr/225' into develop

Fix install issue and update the documentation

+## Branches

+We use the 'master' branch to hold the version currently deployed to the
+production servers. Only hotfixes are applied here.

+Most of development happens based upon the 'develop' branch. So unless
+you are investigating a specific issue that occured in production you
+probably want to base your changes on 'develop':
+```
+git checkout origin/develop -b my-new-feature
+```
+This will create a new branch called 'my-new-feature' based on the develop
+branch from the origin remote.
