 ### Deploying the demo
 
+Build an executable of the [Lab Recruits](https://github.com/iv4xr-project/labrecruits). To do this you can clone or download the source code of this game. Open the project in Unity (note the specific version it needs) and build the executable from there.
+
+For Mac: put the produced `LabRecruits.app` in `gym/Mac/bin`. For Windows: put the produced files including `LabRecruits.exe` in `gym/Windows/bin`.
+
 The demo classes are in `src/test/java/agents/demo`. The demos are by default non-visual (you don't literally see the game runs). Set the variable `TestSettings.USE_GRAPHICS` in the corresponding demo-class to `true` if you want it to be visual.
