 You can use `gojekyll` with the official `danog/gojekyll` image, for example to build the site in the current directory into `_site`:
 
-```
+```bash
 docker run --user $UID:$GID -v $PWD:/app --pull always --rm -it danog/gojekyll build -s /app
 ```

-```
+```bash
 docker run --user $UID:$GID -v $PWD:/app --pull always --network host --rm -it danog/gojekyll serve -s /app
