Help:Section

A page can and should be divided into sections, using the section heading syntax. For each page with more than three section headings, a table of contents (TOC) is automatically generated.

Creation and numbering of sections
Sections are created by creating their headings, as below.

Sub-subsection
Please do not use only one equals sign on a side (| =Heading= ). This would cause a section heading to be as large as the page's name (title).

Heading names of sections (including subsections) should be unique on a page. Using the same heading more than once on a page causes problems:
 * An internal link (wikilink) to a section, in the form Article name, will only link to the first section on the page with that name, which may not be the intended target of the link.
 * When a section with a duplicate name is edited, the edit history and summary will be ambiguous as to which section was edited.
 * When saving the page after a section edit, the editor's browser may navigate to the wrong section.

Section editing
Sections can be separately edited by clicking special edit links labeled "[edit]" by the heading.

Subsections
Subsections are included in the part of the section that is edited. Section numbering is relative to the part that is edited, so on the relative top level there is always just number 1, relative subsections all have numbers starting with 1: 1.1., 1.2, etc.; e.g., when editing subsection 3.2, sub-subsection 3.2.4 is numbered 1.4. However, the heading format is according to the absolute level.
