+## Community templates
+
+The CLI also supports installing templates developed by the community using a GitHub repository URL or `owner/repo` specifier. These templates are maintained outside the CLI, so you should review the source code before using them in your project.
+
+Here are some of the available community templates:
+
+### Tailwind + React Router
+

+
+```sh
+pnpm create @dhis2/app my-app --template https://github.com/derrick-nuby/dhis2-ts-tailwind-react-router
+```
