How can we create a custom mod?

[Samapple31]

Hi there guys! I was just thinking of how some Rimworld players can create custom mods (not allowed this time). Can we make custom mods with weapons, items, etc that aren't in standard vanilla 1.2 and can we also make a Rimworld mod editor software app please? This may be updated soon. Anyway, thanks for viewing this message!
