While checking repositories on Github, you can mark them as "Watching". This will send you notifications whenever something happens in that repository, e.g. the author makes a commit, releases a new version, etc...

There is also an extension for most internet browsers that warns you if got any notifications on Github.

Tortoise Git does exactly that: https://tortoisegit.org/
