@dadiorchen also can u plz add this docker helper script to our documentation

docker run --init -v $(pwd)/themes/treetracker:/opt/keycloak/themes/treetracker -p 8080:8080 -e KEYCLOAK_ADMIN=admin -e KEYCLOAK_ADMIN_PASSWORD=password -e KC_CACHE_THEMES=false -e KC_CACHE_TEMPLATES=false ${your-docker-image-name}

it basicaly reloads the theme config in the docker image, whenever we make any change to theme config.
