 It is strongly disrecommended to run the production using this command. Instead, please refer to the [Quart deployment docs](https://pgjones.gitlab.io/quart/tutorials/deployment.html).
 
+## Subscriptions
+
+If you would like to display the latest videos from your favorite channels/accounts on the homepage, simply place your subscriptions in `accounts.list` or `channels.list` files, like so:
+
+```
+# Comments are allowed in here with a # marker
+# Each entry can be one of:
+#   - user@server
+#   - @user@server
+#   - http(s)://server/a/user (accounts.list only)
+#   - http(s)://server/c/channel (channels.list only)
+```
+
 ## TODO
 
 - Federation errors (eg. name not resolving) are not handled properly, producing bloaty tracebacks server side and unfriendly errors client side
 - Expects to run in the webroot, not in a subdirectory
 - Relies on search.joinpeertube.org API, while we should be able to configure a different SepiaSearch instance
+- Search result uses `{{ domain }}` instead of actual result-related domain
+- Cache should be persisted across runs? Especially since simply running main.py reloads the server every time a python file is saved to disk
+- Maybe caching of API requests should be handled in peertube.py? subscriptions caching should stay in main.py though
+- Support a mode/theme to act as lightweight frontend for a single instance, maybe reusing real peertube URL format?
+- Missing account/channel picture is not pretty: https://tube.fr.tild3.org/kolektiva.media/accounts/bureburebure/video-channels
+- main.py is starting to be a bit long, with some code duplication
+- Lots of duplication in templates
+- Configurable number of latest videos on homepage

+## Contributing

+Patches should be sent to `~metalune/public-inbox@lists.sr.ht` with git send-email command ([tutorial](https://git-send-email.io/)).
