+### I'm using docker-compose.override.yml and now I'm getting schema update (and other) strange issues
+
+Alternatively, you've changed something related to `/var/www/html/tt-rss` in `docker-compose.yml`.
+
+You screwed up your docker setup somehow, so tt-rss can't update itself to the persistent storage location on startup.

 ### How do I make it run without /tt-rss/ in the URL, i.e. at website root?
 
 You can't, not with this particular setup. I wanted to support both sharing a single domain with other applications and running on a dedicated domain. This was the easiest way to implement it.
