  • . gitignore tells git which files (or patterns) it should ignore. It's usually used to avoid committing transient files from your working directory that aren't useful to other collaborators, such as compilation products, temporary files IDEs create, etc.

  • The .gitignore file is a text file that tells Git which files or folders to ignore in a project.

  • A local .gitignore file is usually placed in the root directory of a project. You can also create a global .gitignore file and any entries in that file will be ignored in all of your Git repositories.

    • '#' is used to add comments to a .gitignore file
