+- Item 1 in `code`

+
+Or ordered:
+
+1. Item 1 in **bold**
+2. Item 2 with some long lines that should wrap: Lorem ipsum dolor sit amet,
+   consectetur adipiscing elit. Aenean ac mattis nunc. Phasellus elit quam,
+   pulvinar ac risus in, dictum vehicula turpis. Vestibulum neque est, accumsan
+   in cursus sit amet, dictum a nunc. Suspendisse aliquet, lorem eu eleifend
+   accumsan, magna neque sodales nisi, a aliquet lectus leo eu sem.

+
+## Code
+
+Both `inline code` and code blocks are supported:
+
+```rust
+/// A rust enum
+#[derive(Debug, PartialEq, Clone)]
+enum Foo {

+    Bar
+}
+```
