+## Removing the Repository
+
+To remove the Bandersnatch repository that you've set up using Docker Compose, follow these steps. Please be aware that this process will delete all the packages and configuration files you have downloaded or created. Ensure you have backups if necessary.
 
-- `docker compose up -d`
+1. **Stop the Docker Containers**: Before removing any files, it's important to stop the running Docker containers to prevent any file corruption or data loss. Use the command:
+```bash
+docker compose down
+```
+
+2. **Remove the Packages and Configuration Files**: To delete all the downloaded packages and configuration files, run the following command. This will remove the `packages` and entire `config` directory directory inside your `config` folder, which contains all the mirrored Python packages.
+```bash
+rm -rf ./data/
+rm -rf ./config/
+```
 
+3. **Clean up Docker Artifacts**: Finally, to remove any Docker volumes, networks, or other artifacts that were created with the Docker Compose file, you can use the following command:
+```bash
+docker system prune --volumes
+```
 ## Caveats
 
 Watch out for your docker MTU settings. Changing the MTU of the daemon is not going to help (see issue #1271).
 Otherwise you might get error messages like these:
 
-```
+```bash
 ERROR: Call to list_packages_with_serial @ https://pypi.org/pypi timed out: Connection timeout to host https://pypi.org/pypi (master.py:218)
