The article discusses the different ways to ignore files in Git, beyond just using the .gitignore file. It highlights three files that can be used to ignore files: .gitignore, .git/info/exclude, and ~/.config/git/ignore. Each file has a different scope, with .gitignore being checked into Git, .git/info/exclude being specific to a repository, and ~/.config/git/ignore being global. The article also provides a command to check which file is ignoring a specific file.
