+    \since 5.14
+    Replaces the entire contents of the document with the given
+    Markdown-formatted text in the \a markdown string, with the given
+    \a features supported.  By default, all supported GitHub-style
+    Markdown features are included; pass \c MarkdownDialectCommonMark
+    for a more basic parse.
+
+    The Markdown formatting is respected as much as possible; for example,
+    "*bold* text" will produce text where the first word has a font weight that
+    gives it an emphasized appearance.
+
+    Parsing of HTML included in the \a markdown string is handled in the same
+    way as in \l setHtml; however, Markdown formatting inside HTML blocks is
+    not supported.
+
+    Some features of the parser can be enabled or disabled via the \a features
+    argument:
+
+    \value MarkdownNoHTML
+           Any HTML tags in the Markdown text will be discarded
+    \value MarkdownDialectCommonMark
+           The parser supports only the features standardized by CommonMark
+    \value MarkdownDialectGitHub
+           The parser supports the GitHub dialect
+
+    The default is \c MarkdownDialectGitHub.
+
+    The undo/redo history is reset when this function is called.
