Scan Title

scanTitle: boolean | string;

Scan the content for the title and inject it into the frontmatter.

• default: false
• true, to have it injected into property title
• <name>, to have it injected as property <name>

The title will be taken from the first heading with depth=1, i.e. the first line # My Title.

If the frontmatter already has a property with that name, it will NOT be overwritten.
