Its really simple open cloudstream and go to their website page where u downloaded their app. From there click repositories, then click install to the repositories you want to download. It will redirect to the app and ask u if you want to download all providers. You could also do it manually and add the url to the app by copying the url. It is very simple and convinient.

Here is the link to the repos: https://cloudstream-on-fleek-co.ipns.dweb.link/repos/
