+# DrawUsingMadGraphics
+
+Use another library `MadGraphics` to draw graphics on the LCD. You'll fill the screen with yellow, draw an orange square in the middle and display the text "Hello world!".
+
+## Library reference
+
+* [SwiftIO](https://github.com/madmachineio/SwiftIO)
+* [MadBoard](https://github.com/madmachineio/MadBoards)
+* [ST7789](https://github.com/madmachineio/MadDrivers/tree/main/Sources/ST7789/ST7789.swift)
+* [MadGraphics](https://madmachineio.github.io/MadGraphicsDocs/documentation/madgraphics/)
+
+
+## How to use
+
+1. Download the MadDrivers folder.
+2. Open and run one of the examples in Visual Studio Code. If you are not familiar with the operation, you could refer to [this tutorial](https://docs.madmachine.io/overview/advanced/run-example).

-# DrawUsingMadDisplay
+# DrawPixels
 
-Use another library `MadDisplay` to draw graphics on the LCD. You'll fill the screen with yellow, draw an orange square on the middle and display the text "Hello world!".
+Fill the LCD with white and draw a red square on the middle.
 
 ## Library reference
 
 * [SwiftIO](https://github.com/madmachineio/SwiftIO)
 * [MadBoard](https://github.com/madmachineio/MadBoards)
 * [ST7789](https://github.com/madmachineio/MadDrivers/tree/main/Sources/ST7789/ST7789.swift)
-* [MadDisplay](https://github.com/madmachineio/MadDisplay)
 
 
 ## How to use
 
 1. Download the MadDrivers folder.
 2. Open and run one of the examples in Visual Studio Code. If you are not familiar with the operation, you could refer to [this tutorial](https://docs.madmachine.io/overview/advanced/run-example).
