Document how to set up customize Vale for custom words and CI

[cbetta]

I would love for there to be some guidance/documentation on how to customize Vale. Specifically, I want to know how to add my own words to the dictionary, and secondly, how to set Vale to be a required check in my CI - right now it seems a neutral check?

To add new words, you need to specify the vocabulary in .vale.ini and then add new words there. See: https://vale.sh/docs/keys/vocab

For example, take a look at Mintlify's own documentation repository: https://github.com/mintlify/docs. In particular, the .vale.ini file and the .vale/ folder.

As for making grammar linter checks (Vale) be required, set them to "Blocking" in the dashboard:
