Git ignore

• .gitignore

The .gitignore file in the root of the repository can describe sets of files that don’t need tracking. This will make sure you don’t add the files by mistake (e.g. while using git add .) and they won’t show up in the output of the git status command.

config.ini
*.html
*.[oa]
*~
*.swp

Add this file to the repository and commit it. This will ensure that no one in the project will have the extra files problem.

You can also have additional .gitignore files in the subdirectories that will only apply to those folders.

There is a good list of gitignore files by programming language and by frameworks maintaind by GitHub.
