You can create headings by starting and ending a line with up to five equal signs. The heading text is between those markers, separated by a single space.

Headings can be automatically numbered, you can enable or disable this for each page (see #pragma section-numbers on HelpOnProcessingInstructions) and for the whole site (see show_section_numbers on HelpOnConfiguration).

For more information on the possible markup, see HelpOnEditing.

Note that proper section numbering requires you to order sections according to a valid structure, i.e. correctly nested. Our sample doesn't do this, so you get a different numbering scheme than you might expect.
