 Clone the repository, install prerequisites manually via pip or your favourite package manager, `python MFOR.py`. Choose your game options (hover over a given option to see a tooltip explaining it), then click Generate. A popup will ask you to open an unmodified copy of the original game. This is not provided with the randomizer for legal reasons.
 
+To build FLIPS (present as a submodule), prerequisites are a C++ compiler, `libgomp` and `libgomp-devel`. Refer to [its README](https://github.com/Alcaro/Flips) for further info.

 The randomizer currently works with **only** the USA/Australia version of the game. To ensure you have the correct version of the game, the CRC32 checksum should be: `6C75479C`
