Basics
Before developing, you need to master some basic Web development knowledge, including:
Install Desktop Widget Client

Install from Microsoft Store
Download from this site
Enable Developer Mode
After opening the desktop widget client, right-click the tray icon in the bottom right corner, then long-press the GitHub icon for 5 seconds to enable Developer Mode

Once enabled, right-clicking on a widget will pop up the DevTools menu

DevTools is consistent with Chrome DevTools, where you can debug web pages.
