+## Cocos2d-like Actions for Unity3d
 
-Cocos2d Actions for Unity3d
+Unity3d is a very good game engine. It's almost perfect for quick prototyping.
+After switching from Cocos2D to Unity3d, i'm still missing just one cocos's feature - actions.
+It's a great combination of simplicity and flexibility, and i haven't found the suitable replacement for it.
+Since actions are quite simple, i implemented them myself.
+
+### Included actions (ready and WIP)
+
+Base actions
+- [x]  Sequence
+- [x]  Parallel
+- [x]  Repeat and Loop *implemented in one action*
+- [ ]  Reverse
+
+Interval actions
+- [x]  MoveTo
+- [x]  MoveBy
+- [x]  RotateTo
+- [x]  RotateBy
+- [x]  ScaleTo
+- [x]  ScaleBy
+- [x]  TintBy
+- [x]  Delay and RandomDelay *implemented in one action*
+- [ ]  TintTo
+- [ ]  FadeOut
+- [ ]  FadeIn
+- [ ]  FadeTo
+- [ ]  JumpTo 
+- [ ]  JumpBy
+- [ ]  Bezier
+- [ ]  Blink
+
+Instant actions
+- [x]  Place *renamed to SetPlace*
+- [x]  CallFunc *renamed to SendMessage*
+- [x]  Hide
+- [x]  Show
+- [x]  ToggleVisibility
+
+### Some additional actions
+
+Interval actions
+- [ ]  SkewBy
+- [ ]  SkewTo
+
+Instant actions
+- [x] SetRotation
+- [x] SetTint
+
+### Future plans
+After completing these actions, i'm going to add some more to the list.
+
+## License
+Just like Cocos2D, this code licensed under the [MIT License](http://en.wikipedia.org/wiki/MIT_License)
+
+## Help and donations
+I'm not doing it to make profit, but if you want, [you can send me a couple of bucks via PayPal](https://www.paypal.com/cgi-bin/webscr?cmd=_s-xclick&hosted_button_id=Z64675TKXFRFU).
+
+Also, if you'll write some action based on mine, feel free to send it to me, if you want me to add it to the library. I'll put your name on this page.
