How to use this .gitignore for C++

Copy the C++ rules above, or download the file directly.
Create a file named .gitignore at the root of your Git repository and paste the rules into it.
If some of those files are already tracked, run git rm -r --cached . then commit again — Git only applies ignore rules to untracked files.
Commit the .gitignore so everyone on the team shares the same rules.
