This rule for remark-lint enforces that headings have a certain number of words. By default, headings must have at least 2 words and at most 10. You can configure this length like this:
{
"plugins": [
"remark-preset-lint-recommended",
["remark-lint-heading-length", ["error", {
"min": 3,
"max": 12
}]]
]
}
This would enforce at least 3 and at most 12 words within the heading of your Markdown files.
