Последняя активность
For re-doing the repo, to take into account your changes to the .gitignore
Remove Stuff that should ignored. (like class files (java) or .pyc files (python)) Don't Store node_modules either!
The series of commands below will remove all of the items from the Git Index (not from the working directory or local repo), and then updates the Git Index, while respecting git ignores. PS. Index = Cache
