I've wanted to try highlight for our company although I find it off putting that new companies market themselves as "Open Source!" "Self Hosted!" but really aren't that accessible or documented for independent use.

I get it. it's a business, and it really is open source (thanks for the permissive license), but it often feels more like an after-thought/marketing play, which is completely fine if you're upfront. or maybe I'm just spoiled.
