Each status code lives in a Markdown file at contents/codes, the easiest way to submit changes is via the GitHub editor. When contributing changes to the status codes please be mindful of the following:

  • Soft line length of 80 for Markdown
  • Markdown links should be used as references instead of inline
  • If an RFC or external document is referenced, make the reference a link
  • Source information on a status code from the most recent standards available (Status Code standards directory is available on
  • The opening paragraph of a status code should describe the meaning, following paragraphs can describe implementation
  • Don't edit the meaning of descriptions, but formatting and structural changes are a-okay
  • Don't double-space after a period, and remove any examples of it
  • If the description references a section in the current RFC, always add the RFC identifier. For example "Section 6.6" should become "RFC1234 Section 6.6"
