An article should start with a simple summary of the topic, then lead the reader into more detail, breaking up the text into manageable sections with logical headings.

The lead

The lead section is the very first part of an article, appearing before the table of contents and any headings. The first sentence of the lead typically contains a concise definition and establishes the topic's notability. The rest of the lead should introduce the article's context and summarise its key points.

The lead section should be one to four paragraphs long and stand alone as a concise overview of the article. The emphasis given to each statement in the lead should roughly reflect its relative importance to the topic. Statements should be carefully sourced if covering material not sourced elsewhere in the article, and should be written in a clear, accessible style to encourage a reading of the full article. The rest of the article's prose will give detail for readers who want more information.

Sections and headings

Articles are organised into sections and subsections, each with a short heading that will automatically appear in the table of contents. In general, sections that are one to four paragraphs long are the most readable.

Headings normally omit an initial "the" or "a", and avoid repeating the title of the article. Typically only the first word in a heading is capitalised (sentence case).

Heading 1 is the article's title and is automatically generated. The section headings in the article start at the second level (==Heading 2==), with subsections at the third level (===Heading 3===), and so on. Sections should not skip levels from sections to sub-subsections (e.g., a fourth-level subsection heading immediately after a second-level heading).
