How to write Yii extensions? Any good reference?

Question

Does anyone know any good reference on how to write Yii framework extensions? I've been searching all over the net and I couldn't find anything.

If there is no such thing, what steps do I need to take (in general) ?

Answer 1

look at the official tutorial

http://www.yiiframework.com/doc/guide/1.1/en/extension.create

I think that is quite enough and good start for creating Yii Extensions
