-Features
---------
-
-All features of Sundown are supported, including:
-
-*   **Compatibility**. The Markdown v1.0.3 test suite passes with
-    the --tidy option.  Without --tidy, the differences are
-    mostly in whitespace and entity escaping, where blackfriday is
-    more consistent and cleaner.
-
-*   **Common extensions**, including table support, fenced code
-    blocks, autolinks, strikethroughs, non-strict emphasis, etc.
-
-*   **Safety**. Blackfriday is paranoid when parsing, making it safe
-    to feed untrusted user input without fear of bad things
-    happening. The test suite stress tests this and there are no
-    known inputs that make it crash.  If you find one, please let me
-    know and send me the input that does it.
-
-    NOTE: "safety" in this context means *runtime safety only*. In order to
-    protect yourself against JavaScript injection in untrusted content, see
-    [this example](https://github.com/russross/blackfriday#sanitize-untrusted-content).
-
-*   **Fast processing**. It is fast enough to render on-demand in
-    most web applications without having to cache the output.
-
-*   **Routine safety**. You can run multiple parsers in different
-    goroutines without ill effect. There is no dependence on global
-    shared state.
-
-*   **Minimal dependencies**. Blackfriday only depends on standard
-    library packages in Go. The source code is pretty
-    self-contained, so it is easy to add to any project, including
-    Google App Engine projects.
-
-*   **Standards compliant**. Output successfully validates using the
-    W3C validation tool for HTML 4.01 and XHTML 1.0 Transitional.
