Configuration

fmm will check the current directory and the previous directory for a Factorio installation. If neither is valid, it will fall back to the directory specified by the FACTORIO_PATH environment variable.

If the mods directory is not contained within the game data directory (i.e. you installed via Steam), specify the FACTORIO_MODS_PATH environment variable to point fmm to the correct mods directory.

For uploading mods, specify your API key with the FACTORIO_API_KEY variable.

If you have logged in to your Factorio account, fmm will automatically pull your username and token from the player-data.json file. Alternatively, you can specify them with FACTORIO_USERNAME and FACTORIO_TOKEN respectively.
