To specify a (sub-) section of a zettel, you should use the headings syntax: at the beginning of a new line type at least three equal signs (""''=''"", U+003D), plus at least one space and enter the text of the heading as [[inline elements|00001007040000]]. ```zmk === Level 1 Heading ==== Level 2 Heading ===== Level 3 Heading ====== Level 4 Heading ======= Level 5 Heading ======== Level 5 Heading ``` This renders in HTML as: :::example === Level 1 Heading ==== Level 2 Heading ===== Level 3 Heading ====== Level 4 Heading ======= Level 5 Heading ======== Level 5 Heading ::: === Notes The heading level is translated to a HTML heading by adding 1 to the level, e.g. ``=== Level 1 Heading``{=zmk} translates to ==

Level 1 Heading

=={=html}. The ==

=={=html} tag is rendered for the zettel title. This syntax is often used in a similar way in wiki implementation. However, trailing equal signs are __not__ removed, they are part of the heading text. If you use command line tools, you can easily create a draft table of contents with the command: ```sh grep -h '^====* ' ZETTEL_ID.zettel ```
