+# Judge Language Customization
+
+1. Build custom judge server container image
+
+   If you don't need to modify judge environment, you can skip this step.
+
+   ```bash
+   git clone https://github.com/QingdaoU/JudgeServer.git
+   cd JudgeServer
+   # modify
+   docker buildx build . -t oj-judge --load
+   ```
+
+2. Download [languages.py](https://raw.githubusercontent.com/QingdaoU/OnlineJudge/master/judge/languages.py) to the deploy folder.
+
+3. Edit and mount the languages.py
+
+   ```yaml
+   services:
+     # ...
+     oj-backend:
+       # ...
+       volumes:
+         - ./data/backend:/data
+         - ./languages.py:/app/judge/languages.py:ro
+   ```
+
+4. Start containers
+
+   ```bash
+   docker compose up -d
+   ```
+
+5. Overwrite judge language config in database from mounted languages.py
+
+   ```bash
+   docker compose exec oj-backend python manage.py shell <<EOF
+   from options.options import SysOptions
+   SysOptions.reset_languages()
+   EOF
+   ```
