+# API Notation Syntax for Vim
+
+This is a syntax for api notation, a simple notation I've been using for
+annotating module APIs in specs and other documents.
+
+## API Notation Reference
+
+The most recent reference as of now is in this [gist][api-reference], so
+check that to be sure. But here's a reproduction of the notation.
+
+```
+Class Members
+ + class property
+ - instance property
+ ~> listened events (socket)
+ +> listened events (class/module)
+ -> listened events (instance)
+ <~ dispatched events (socket)
+ <+ dispatched events(class/module)
+ <- dispatched events (instance)
+ :: class method
+ # instance method
+
+Other symbols
+ => returns
+->() callback return
+[xx] optional
+<xx> data type
+
+Recommended order: class first, then sockets, then instance. Internally:
+Properties, events, methods.
+```
+
+## How does it look like?
+
+Like this.
