+# Hello Code Sample
+
+This is a Hello World example that shows you how to use VS Code API.
+
+Guide for this sample: https://vscode-ext-docs.azurewebsites.net/api/hello-code/introduction.
+
+## Demo
+
+![demo](demo.gif)
+
+## VS Code API
+
+### `vscode` module
+
+- [`commands.registerCommand`](https://code.visualstudio.com/docs/extensionAPI/vscode-api#commands.registerCommand)
+- [`window.showInformationMessage`](https://code.visualstudio.com/docs/extensionAPI/vscode-api#window.showInformationMessage)
+
+### Contribution Points
+
+- [`contributes.commands`](https://code.visualstudio.com/docs/extensionAPI/extension-points#_contributescommands)
+
+## Running the Sample
+
+- Run `npm install` in terminal to install dependencies
+- Run the `Run Extension` target in the Debug View. This will:
+	- Start a task `npm: watch` to compile the code
+	- Run the extension in a new VS Code window
