 ## Inputs
 
 - `last-tag` (optional): Starting tag to increment from. If not provided, uses the latest tag in the repository.
 - `token` (required): GitHub token for repository access. Use `${{ github.token }}` for public repos or a PAT for private repos.
+- `prerelease` (optional): Whether to create a prerelease tag with `-rc-<github.sha>` suffix. Defaults to `false`.
+- `max-tags` (optional): Maximum number of tags to fetch when looking for the latest non-pre-release tag. Defaults to `50`.
 
 ## Outputs
 
-- `new-tag`: The incremented semantic version tag (e.g., `1.2.3`)
+- `new-tag`: The incremented semantic version tag (e.g., `1.2.3` or `1.2.3-rc-abc123` for prerelease)
