+  🚀 How to update to the new Official Puppet VS Code Extension
+---
+
+The Puppet extension is 🚚 moving! We are changing from `jpogran.puppet-vscode` to `puppet.puppet-vscode` in the VS Code Marketplace! Check out the [puppet blog post](https://puppet.com/blog/whats-new-with-the-puppet-vscode-extension) for more information on why.
+
+The new extension can be found at [Puppet VS Code](https://marketplace.visualstudio.com/items?itemName=puppet.puppet-vscode). Note that the `jpogran.puppet-vscode` extension will no longer receive updates.
+
+## How to Update to the new Extension
+
+In order to use the new extension, you can install it using the [normal installation methods](https://code.visualstudio.com/docs/editor/extension-gallery) or you can can also update it from the commandline by running the following commands:
