 ## Making your lesson citable
 You can add information about how people should cite your lesson by adding a citation file to your lesson repository. If the root folder of your lesson project includes a file called `CITATION` or `CITATION.cff`, the _'Cite'_ page footer of your lesson site will link to this file.
