Questions specifically about configuration files other than the init file. Do not use this tag for questions about how to configure something, only for questions specifically about the configuration files.
Use this tag for questions about configuration files for Emacs features and add-ons. For questions specifically about
.emacs.d/init.el, use the tag init-file instead. For questions that ask “how do I configure X?”, just use the tag(s) for X: use this tag only for questions where the configuration files themselves are the issue.
