+# 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 [ATX headings][] and [semantic linewrapping][].
+
+Use [reference links] (shortcut style where possible),
+with its reference definition at bottom of same section.
+
+Avoid [hard line breaks][].
