Visual Studio Code is built with extensibility in mind. From the UI to the editing experience, almost every part of VS Code can be customized and enhanced through the Extension API. In fact, many core features of VS Code are built as extensions and use the same Extension API.

This documentation describes:

• How to build, run, debug, test, and publish an extension
• How to take advantage of VS Code's rich Extension API
• Where to find guides and code samples to help get you started
• Following our UX guidelines for best practices

Code samples are available at Microsoft/vscode-extension-samples.
