# onlyoffice ## Fonts If you want to add fonts, place the font folder in ttf, and then add a file called `docker-compose.override.yml`: ``` version: '2' services: onlyoffice: volumes: - ./ttf/Cairo:/usr/share/fonts/truetype/Cairo - ./ttf/Roboto_Slab:/usr/share/fonts/truetype/Roboto_Slab ``` Then restart the container, and ask your users to update their browser [cache](https://github.com/ONLYOFFICE/DocumentServer/issues/329).
