+It provides a shared library (`libcmark`) with functions for parsing
+CommonMark documents to an abstract syntax tree (AST), manipulating
+the AST, and rendering the document to HTML or to an XML
+representation of the AST.  It also provides a command-line program
+(`cmark`) for parsing and rendering CommonMark documents.
+
+The library and program are written in standard C99 and have
+no library dependencies. The parser is very fast, on par with
+[sundown]:  see the [benchmarks].
+
+It is easy to use `libcmark` in python, lua, ruby, and other dynamic
+languages: see the `wrappers/` subdirectory for some simple examples.
