 On your first run, accessing `<your ip>:8056` will bring you to the setup wizard.
 
-Before you start configuring, you should make sure that timezones are correct everywhere. If you're running bare metal, this shouldn't be an issue, but docker containers are another story. For linuxserver.io Jellyfin containers, you should be able to use `-e TZ=Europe/London` but if not, `-v /etc/localtime:/etc/localtime:ro` works almost every where. Once you've added this run `docker exec -it <your container> bash` to enter its shell, then `date`. From there you can see if the time is correct.

+## New account defaults
+jf-accounts can store a users policy (library access, perms, etc.) and homescreen layout, and write them to all new users. Setting this up hasn't been implemented in the web UI setup yet, so you need to do this from the command line if you want it.
+
+If you're running on bare metal, run
+
+`root@lab ~# jf-accounts --get_defaults`
+
+If you're using docker, make sure the container if already running and then run
+
+```
+root@lab ~# docker exec -it <your container name> bash
+root@ed2244cc8ab4:/# jf-accounts -d /data --get_defaults
+```
+
+After that, follow through the prompts to store your defaults.

   * Best practice is to create a separate admin account (I named mine 'accounts') without normal privileges (accessing media, etc.). Its credentials can then be entered.

   * Because one will most likely use jellyfin-accounts behind a reverse proxy, it has no way of knowing the URL it will be accessed from. The email sent out includes a link to the invite page, so `url_base` stores the location of the invite path, e.g `https://jellyf.in:8056/invite`.
