+## Adding Teams
+
+Any Rust team can have a section in the Rust Forge. If you'd like to add your team you first need to add them as an item to `src/SUMMARY.md`, like so replacing `TEAM NAME` with your respective team's name to show on forge, and `<TEAM_NAME>` with a filesystem and url friendly version of that name where your documentation will be stored.
+
+```markdown
+- [TEAM NAME](src/<TEAM_NAME>/README.md)
+<!-- or -->
+- [TEAM NAME](src/<TEAM_NAME>.md)
+```
+
+ If you run `mdbook build`, `mdbook` will automatically create the folder and file for your team.
+ 
+ It's recommended that you put general team information in `src/<TEAM_NAME>/README.md` such as where the meetings happen, repositories that the team manages, links to chat platforms, etc. Larger topics such be made as a subpage.
+
+```markdown
+- [TOPIC](src/<TEAM_NAME>/TOPIC.md)
+```
