 ## Usage
-this is primarily a library for creating hooks and middleware for your own libraries.  Here is an example of a class that is extended using hookified.
+This was built because we constantly wanted hooks and events extended on libraires we are building such as [Keyv](https://keyv.org). This is a simple way to add hooks and events (via [emittery](https://npmjs.com/package/emittery)) to your libraries.
