+### Git-Based Collaboration
+
+Every project and request is stored as a plain JSON file under `~/.local/share/cz.bugsy.roster/projects/`. This makes it straightforward to share your API collections with a team:
+
+```bash
+# Put your Roster data directory under version control
+cd ~/.local/share/cz.bugsy.roster/projects
+git init
+git remote add origin git@example.com:your-team/api-collections.git
+git add .
+git commit -m "Add API collections"
+git push
+```
+
+Team members can then clone the repository into their own data directory and get the full set of projects and requests instantly. Changes to requests show up as clean, reviewable diffs — each request is a separate file, so there are no merge conflicts from unrelated edits.
+
 ### JavaScript Automation
