remark-lint-heading-length

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.
