Ignoring Files in Git

1. Create a file named .gitignore horizontal to (i.e. in the same directory as) your git repository. You will need to enable hidden files or use $ ls -a to see it.
2. Open .gitignore in your text editor.
3. List the files or folders you want git to ignore, one per line.
4. Add and commit the .gitignore file to git.
5. (Optional) If you have already committed the files you want to ignore, you will need to tell git to forget about them:

# Replace `<file-or-folder>` with the name of the file or folder you want git to
forget about.
$ git rm --cached <file-or-folder>
