 # Windows Build Machines
 Setting up a Windows build machine consists of a few steps:
 1.  Install the Unreal Engine
-2.  Install MinGW or equivalent to get `envsubst` command
-3.  Install the gitlab runner service and register a gitlab runner. Prefereably a shared runner. Use executor `shell`. Use the tags `windows` and `unreal-4.21`(replace version number) for the runner. Make sure to specify a user for the `gitlab-runner install` call, such that the service is not running as admin afterwards.
-4.  Configure the gitlab runner. For this open the config.toml file and add the following lines (change path to unreal engine folder):
+2.  Follow [these instructions](https://answers.unrealengine.com/questions/112733/how-to-move-derived-data-cache-folder.html#answer-552735) to set the derived-data-cache directory to the build directory
