Quick Start
Open https://makecode.microbit.org/
New Project
Enter a project name and click Create.
After entering the editor interface we can see Micro:bit Simulator，Toolbox，Workspace。
Add Proprietary Extension Libraries
In order to program Nezha Pro, we need to add an extension library. Find “Extensions” in the code drawer and click on it.。
A dialog box will pop up, search for “nezha2” and click on download the code base.
Note: If you get a prompt that some codebase will be removed for incompatibility reasons, you can either follow the prompt and continue, or create a new project inside the project menu bar
