How to Install VS Code Extensions Without the Marketplace (.vsix)

Install any .vsix extension directly into VS Code without publishing to the marketplace. Works on VS Code, Cursor, VSCodium, and Code Server.

Installing .vsix Extensions

All YFIN Code VS Code packs are distributed as .vsix files — the standard VS Code extension format. You don't need marketplace approval to install them.

Method 1: VS Code UI

1. Open VS Code

2. Click the Extensions icon in the sidebar (or Ctrl+Shift+X)

3. Click the ··· menu (top right of the Extensions panel)

4. Select Install from VSIX...

5. Pick your .vsix file → Done

Method 2: Command Line

```

code --install-extension 06-vscode-dark-gold-theme.vsix

```

This works on VS Code, Cursor, and VSCodium by replacing `code` with the appropriate command.
