+## Chaikin
+
+### Instructions
+
+Implement the [Chaikin's](http://graphics.cs.ucdavis.edu/education/CAGDNotes/Chaikins-Algorithm/Chaikins-Algorithm.html) algorithm step by step in an animation.
+
+The objective is to create a canvas where the user will draw 1 or more and then the screen will play an animation of each step to get to the final result of a curve drawn using the `Chaikin's` algorithm. You can see [here](https://youtu.be/PbB2eKnA2QI) a demo of how the application should work.
+
+- Functionality:
+
+  - The canvas should receive input from the mouse: the user of the program should be able to use the left button to select the control point for the `Chaikin's` algorithm
+
+  - After pressing `Return` should start the animation of the steps until reaching the 7th step of the `Chaikin's` algorithm.
+
+  - Pressing `Escape` should quit the window.
+
+### Note
+
+You are free to use any library for creating and handling window creation, rendering, keyboard and mouse events.
+
+### Bonus
+
+- Add the ability to clear the screen and add new control points.
+
+- Make possible to drag the control points in real time.

+#### Functional
+
+##### Run the program using `cargo run`
+
+###### Does it compile and run without any warnings?
+
+##### Left click in three different positions in the canvas
+
+###### Does the program draw a small circle surrounding the area where you clicked?
+
+##### Press `Return`
+
+###### Does the animation of the Chaikin's algorithm starts?
+
+###### Does the animations the animation completes 7 steps before starting again?
+
+##### Press `Escape`
+
+###### Does the program exit without errors?
+
+##### Run the program again and this time press `Return` without selecting any points
+
+###### Is the program still running?
+
+##### Bonus
+
+###### +Are you able to clear the screen and add new control points without killing and relaunching the program?
+
+###### +Are you able to drag the control points in real time and get a new curve?
