+Advantages of this library:
+
+- **Portable.**  The library and program are written in standard
+  C99 and have no external dependencies.  It has been tested with
+  MSVC, gcc, tcc, and clang.
+
+- **Fast.** Performance is on par with the fastest existing
+  Markdown parser, [sundown]:  see the [benchmarks].
+
+- **Accurate.** The library passes all CommonMark conformance tests.
+
+- **Robust.** The library has been extensively fuzz-tested using
+  american fuzzy lop.  The test suite includes pathological cases
+  that bring many other Markdown parsers to a crawl (for example,
+  thousands-deep nested bracketed text or block quotes).
+
+- **Flexible.** CommonMark input is parsed to an AST which can be
+  manipulated programatically prior to rendering.
+
+- **Multiple renderers.**  Output in HTML, groff man, CommonMark,
+  and a custom XML format is supported. And it is easy to write new
+  renderers to support other formats.
+
+- **Free.** BSD2-licensed.
 
 It is easy to use `libcmark` in python, lua, ruby, and other dynamic
 languages: see the `wrappers/` subdirectory for some simple examples.
