+==================
+
+Mongoose plugin adding lifecyle events on the model class.
+
+Installation
+------------
+
+Add the plugin as a dependency to your project in `package.json`:
+
+```javascript
+{
+  "name": "myproject",
+  ...
+  "dependencies": {
+    "mongoose": "2.6.5",
+    "mongoose-lifecycle": "1.0.0",
+    ...
+  },
+}
+```
+
+And run `npm install` again.
+
+Usage
+-----
+
+Initialization is straightforward:
+
+```javascript
+var Book = new Schema({ ... });
+Book.plugin(require('mongoose-lifecycle'));
+```
+
+Now the model emits lifecycle events before and after persistence operations:
+
+ - beforeInsert
+ - afterInsert
+ - beforeUpdate
+ - afterUpdate
+ - beforeSave (called for both inserts and updates)
+ - afterSave (called for both inserts and updates)
+ - beforeRemove
+ - afterRemove
+
+You can listen to these events directly on the model.
+
+```javascript
+var Book = require('path/to/models/book');
+Book.on('beforeInsert', function(book) {
+  // do stuff...
+});
+```
