+## API Notation
 
-The following document attempts to define a legend for easy specification of APIs for components. Any suggestions to improve are welcome.
+API Notation is a language-agnostic notation to share the public API of components in code. It was created to standardize software specification documents in teams that need to review code across several languages.
 
+## Reference
+The notation allows describing objects or modules, with properties, events and methods along with their types.
 ```
+// Anything after two forward slashes is a comment
 NameOfClass.WithPossibleNamespace
    + class property
    - instance property

-Recommended order: class first, then sockets, then instance. Internally: Properties, events, methods.

-  +staticProperty <String>
-  +anotherStaticProperty <Boolean>
-  ::toggleAnotherStaticProperty()
-  ::setStaticProperty(newValue <String>)

-Here's another example but with events.
+## Example
+With this artificial example, you can see how to use it for more complex cases:
 
 ```
