+
+This handbook is a living document, and all MEDLab team members are invited to edit and improve it.
+
+To contribute, make sure you are in the [MEDLab Contributors](https://git.medlab.host/org/MEDLab/teams/medlab_contributors) team. If you're not, let Nathan know.
+
+Once in that team, navigate to the page you want to edit. To edit, press the pencil-shaped edit icon. If it is not clickable, you may not be in the MEDLab Contributors team.
+
+Once you press the edit icon, you should see an editable text field. Make your changes in Markdown---[syntax is here](https://docs.gitea.com/usage/markdown).
+
+When your edits are complete, go to the bottom of the page to "Commit Changes." Type a simple summary of your changes in the top field. Choose "Commit directly to the `main` branch" and press the "Commit Changes" button.
