To lint all Markdown files in a project:

- uses: DavidAnson/markdownlint-cli2-action@v7
  with:
    globs: '**/*.md'

To lint specific Markdown files in a project:

- uses: DavidAnson/markdownlint-cli2-action@v7
  with:
    globs: |
      README.md
      CHANGELOG.md
      docs/*.md

To fix supported issues when linting:

- uses: DavidAnson/markdownlint-cli2-action@v7
  with:
    command: fix
    globs: '**/*.md'

To specify a custom configuration file:

- uses: DavidAnson/markdownlint-cli2-action@v7
  with:
    command: config

See example.yml for a simple GitHub workflow that uses markdownlint-cli2-action.

See changed.yml for a GitHub workflow that lints only the Markdown files that changed in the most recent commit (useful for Pull Requests and/or gradually introducing linting rules to a new repository).
