Factorio: Difference between revisions

The NixOS module for Factorio supports [https://wiki.factorio.com/Modding third-party modifications], or <i>mods</i>, which are just zip files with extra game content. While technically you can create a full derivation for mods, in practice this can get complicated, especially since authentication is required to download mods from the official mod site.

Instead, you can download the mods you need separately from https://mods.factorio.com/, place them in a folder such as <code>/home/username/factorio-mods</code>, and put this code in your [[Overview_of_the_NixOS_Linux_distribution#Declarative_Configuration|NixOS configuration]].
