# Maintenance of feature structure Writing style of documentation files, coding style of scripts, and how to handle translation, preview, and compilation. ## Documentation Texts are written in [CommonMark][] - a strict flavor of Markdown. Use short [ATX headings][], and [semantic linewrapping][]. Use [reference links] - in shortcut style where possible, with its reference definition at bottom of same section. Avoid [hard line breaks][]. [CommonMark]: "CommonMark - strongly defined, highly compatible specification of Markdown" [ATX headings]: "ATX headings - header markup using leading hashtags" [semantic linewrapping]: "semantic linewrapping - wrap by paragraph or shorter semantic chunks" [reference links]: "reference links - link markup with metadata in separate source paragraph" [hard line breaks]: "hard line breaks - markup to force linebreak within a paragraph"
