 ### Spell checking

+**You need a `[spelling](https://vale.sh/docs/topics/styles/#spelling)` style in your Vale configuration to enable spell-checking**.
 
-With no additional Vale configuration, the spell checker uses a Hunspell-compatible US English dictionary. If you want to use other custom dictionaries, then add and configure [a `spelling` style](https://vale.sh/docs/topics/styles/#spelling) with custom dictionaries.

 The extension doesn't support adding words to dictionaries. For now, the best option is to add them to ignore files or filters as described in the [Vale documentation](https://vale.sh/docs/topics/styles/#spelling).
