My issue was trying to figure out how to articulate it late at night ;)
I think the issues started with completely blowing past the hey you need to install this stuff first section of the README and just starting to get the local build working with stuff like api keys and bundle install. And since I was having issues with the ruby version, I was inclined to think all my issues were around ruby rather than the db.
The biggest thing after needing it installed was needing to have it run before running anything. The installation was lumped with installing things like bundle and yarn which are more hands-off, so it wasn't clear that after installing the prereqs, I should actually start the db and that it wasn't handled in the bin scripts like everything else.
Then I wanted to actually see what was in the db, so I hunted through the configs and internet to see how to find the settings of the db that's created to connect to it within RubyMine.
It wasn't anything really hard or missing, just stuff that wasn't obvious as someone not in the stack.
