+## Setup
+```bash
+docker compose up -d
+```
+
+The web interface can be accessed via http://<ip_address>:3000. Do not use reverse proxy during the initial configuration.
+
+After the configuration process has been completed and the reverse proxy has been set up, change the ROOT_URL of the application in the configuration file:
+
+```bash
+/mnt/gitea/data/gitea/conf
+```
+
+```bash
+- ROOT_URL = http://<ip_address>:3000/
++ ROOT_URL = https://<domain>/
+```
+
+Leave everything else unchanged!
+
+## Notes
+
+By default, the application will run as uid==1000 and gid==1000.
