How do I use the module?

[0x4d6165]

I'm probably making a silly error but I'm not sure how to use the module? I add it to my flake and I still get a

error: The option home-manager.users.maedayscout.programs.firefox.arkenfox does not exist. Definition values:
       - In /nix/store/n97rpbbqjprlyqwcwa09gl88isgbvmz2-source/flake.nix:

You need to import the home manager module into your config at some point. One way to do it is to add imports = [ arkenfox.hmModules.default ]; in your home-manager config.
