Factorio Forums

Greetings, I am new to this site and so far I don't understand much.
I have registered on your website to download a certain mod
But I can't download, writes an error "Your need to own Factorio to download mods"
I don't understand how to solve this problem...

Do you own the game on steam? If so, you need to link your steam account to the factorio account on the website and then it will allow you to download mods. Otherwise you can download them in-game and it will automatically use your steam login to authenticate.
