dacur / gitignore

Last active August 29, 2015 14:06

Create a .gitignore file after creating a new rails app and BEFORE committing! http://stackoverflow.com/questions/1274057/making-git-forget-about-a-file-that-was-tracked-but-is-now-in-gitignore See here for more info: https://help.github.com/articles/ignoring-files

	Create a local .gitignore

	If you create a file in your repository named .gitignore, Git uses it to determine which files and directories to ignore, before you make a commit.

	A .gitignore file should be committed into your repository, in order to share the ignore rules with any other users that clone the repository.

	GitHub maintains an official list of recommended .gitignore files for many popular operating systems, environments, and languages in the github/gitignore public repository.

	In Terminal, navigate to the location of your Git repository.
	Enter: touch .gitignore to create a .gitignore file.
