Using Vale — Fern

What is Vale?

Vale is an open-source tool for linting content from a variety of different file types, including Markdown.

Using Vale with MDX

Once installed, you can use Vale with MDX files by adding a .vale.ini file to your Fern repo.

Be sure to add

[formats]
mdx = md

to your .vale.ini configuration so the MDX format is recognized.

To use Vale’s HTML-style comments () in an MDX file, wrap within an MDX-styled comment ({/* comment */}). For example:

disable Vale: {/*  */}
enable Vale: {/*  */}
