The CodeGrade filesystem has to be installed and both the cgfs and the cgapi-consumer helper program must be available from the user’s $PATH to successfully install and use the CodeGrade editor plugins.

Installing the CodeGrade Atom Plugin (or CodeGra.Atom) can be done via the command line or using the Atom GUI.

Installation via the command line is done with the following command: apm install codegrade-atom.

Installing using the Atom GUI can be done in the Install tab in the Settings or Preferences screen. Search for codegrade-atom in the search dialog and press Install to install the plugin.
