 Components
 ==========
 
-Components are the main building blocks in Yii applications. Components are instances of [[yii\base\Component]]
-or it child class. They support features such as [properties](concept-properties.md), [events](concept-events.md) and
-[behaviors](concept-behaviors.md), which makes them more customizable and easier to use. For example, you may use

 If your components do not need these two features, you may consider extending your component class from

 When extending your class from [[yii\base\Component]] or [[yii\base\Object]], it is recommended that you follow
 these conventions:
 
-- If you override the constructor, specify a `$config` parameter as its *last* parameter and pass this parameter
+- If you override the constructor, specify a `$config` parameter as the constructor's *last* parameter, and then pass this parameter

-- Call parent constructor at the end of the constructor.
-- If you override the [[yii\base\Object::init()]] method, make sure you call the parent implementation.
+- Always call the parent constructor *at the end* of your overriding constructor.
+- If you override the [[yii\base\Object::init()]] method, make sure you call the parent implementation of `init` *at the beginning* of your `init` method.

 The [[yii\base\Object]] class enforces the following object lifecycle:
 
-1. Pre-initialization within constructor. You can set default property values here.
-2. Configuring object with `$config`. The configuration may overwrite the default values set above.
-3. Post-initialization within [[yii\base\Object::init()|init()]]. You may override this method
-   and do sanity check and normalization of the properties.
