htmlhint

Regex-based linter: https://github.com/yaniswang/HTMLHint

htmllint

Uses htmlparser2-based linter: htmllint.

Requires you to have a config file like this default .htmllintrc.

markdown-toc

By default, a table of content will be inserted in your repo root README.md, injecting the TOC on lines containing the HTML comment <!-- toc -->.

When the TOC is added or updated, the hook will fail with Files were modified by this hook. You then just have to git add your README.md and commit again (or git commit -a).

dockerfile_lint

Simply call the latest version of dockerfile_lint
