About vscode-mermAId

[!NOTE]
Starting in VS Code 1.109 support for mermaid diagrams is built into VS Code! Therefore this extension is no longer maintained.

Description

Collaborate with GitHub Copilot to create Mermaid diagrams through the chat participant, @mermAId.

This extension was built in part to demonstrate the power of new GitHub Copilot extension APIs. Check out the VS Code Chat Participant API for more info!
