+Third-party components are handled as git submodules which have to be initialized first. So aside from the regular git checkout invoking `git submodule update --init` or a similar command is needed, for details see Git documentation.
+
+Several apps that are included by default in regular releases such as [First run wizard](https://github.com/nextcloud/firstrunwizard) or [Activity](https://github.com/nextcloud/activity) are missing in `master` and have to be installed manually by cloning them into the `apps` subfolder.
+
+Otherwise, git checkouts can be handled the same as release archives, by using the `stable*` branches. Note they should never be used on production systems.
