 GENERALLY SPEAKING, running as a Docker container is simpler, as you won't have to be concerned about installing Python, or support libraries, or any possible system conflicts generated by those actions.
 
+HOWEVER, you will have to give careful consideration to mapping directories into the container.
+
 For this reason, it's generally recommended that you install via Docker rather than directly on the host.
 
 If you have some specific reason to avoid Docker, or you prefer running it as a Python script for some particular reason, then this general recommendation is not aimed at you.  It's aimed at someone who doesn't have an existing compelling reason to choose one over the other.

+IMPORTANT: If you are running this in Docker, remember that these settings are being read *inside the container*, so, for example, `PLEX_PATH` cannot be a path on the host.  You will need to map directories into the container [as shown in the docker run command above], then use those mapped directories in the `.env`.  Similarly, the URL may need to change depnding on how you have Docker networking set up.  An address on your LAN may not work.
