 That said, there are a few caveats to consider when using a Docker-ized version of this command:
 
-- **Port Publishing**  
+- **Port Publishing**
   The _Dockerfile_ exposes port 8080 from the container, but you must bind to `0.0.0.0` rather than the default `127.0.0.1` (localhost) when running the HTTP server interface, or connectivity won't work from the host.
 
-- **Data Persistence**  
+- **Data Persistence**
   If you actually want to persist your tiddlers, you'll need to [get them out of the container][]; you can use either volumes or bind mounts. In the container, there is a predefined data volume under `/tiddlywiki` that is used as the default working directory.
 
-- **Ownership Permissions**  
+- **Ownership Permissions**
   If you do use a _bind mount_, don't forget that the process running within the **container** will change the **host** filesystem. You should run the container with the `--user` option so that files are created with the desired ownership.
 
 To facilitate handling these things, you can write short wrapper scripts for common scenarios...
