 The system fonts installed on the server are used for burning in subtitles and rendering cover images. How to install them depends on the operating system.
 
+### Server Fonts in Docker
+
+If you are running Jellyfin in Docker, it is possible to pass fonts you have on the host system into the Jellyfin container.  Simply add two additional volumes for /usr/share/fonts and /usr/share/fontconfig and map them to the same path inside the container.
+
+**Docker Compose Example**
+
+```yml
+    volumes:
+      - /usr/share/fonts:/usr/share/fonts
+      - /usr/share/fontconfig:/usr/share/fontconfig
+```
+
+**Docker Command Line Example**
+
+```sh
+ --volume /usr/share/fonts:/usr/share/fonts
+ --volume /usr/share/fontconfig:/usr/share/fontconfig
+```

 ### Client Side System Fonts
 
 The system fonts installed on the client devices are used to display the text in the client interface as well as render subtitles for some clients. How to install them depends on the operating system.
