+### Stubs
+
+TGScraper can also generate class stubs that you can use in your library. A sample implementation is available in the [Sysbot API module](https://github.com/Sysbot-org/Sysbot-api).
+
+Create stubs in the `out/` directory using `Sysbot\Api` as namespace prefix:
+
+```bash 
+  $ vendor/bin/tgscraper app:create-stubs --namespace-prefix "Sysbot\Api" out
 ```
