So I am signed in github and I fork a project . Will my forked repo get updated everytime the original repo updates ? Or should I do forking from the original repo everytime so
When you want to get updates from the original version and merge these with your version, you can use the git pull command. More info is on this here: https://docs.github.com/en/free-pro-team@latest/github/getting-started-with-github/github-glossary#pull
If you choose to fork a repository it copies this repository to your profile. It is essentially the same as cloning but with a fork, a connection between your 'forked' version and the original version is maintained (for pull requests).
This is a very quick and simple description. There is more info here: https://github.community/t/the-difference-between-forking-and-cloning-a-repository/10189
