+![](https://img.shields.io/badge/version-0.3.0-blue)

-## Features
-
-Describe specific features of your extension including screenshots of your extension in action. Image paths are relative to this README file.
-
-For example if there is an image subfolder under your extension project workspace:
-
-\!\[feature X\]\(images/feature-x.png\)
-
-> Tip: Many popular extensions utilize animations. This is an excellent way to show off your extension! We recommend short, focused animations that are easy to follow.
-
-## Requirements
-
-If you have any requirements or dependencies, add a section describing those and how to install and configure them.
-
-## Extension Settings
-
-Include if your extension adds any VS Code settings through the `contributes.configuration` extension point.
-
-For example:
-
-This extension contributes the following settings:
-
-* `myExtension.enable`: Enable/disable this extension.
-* `myExtension.thing`: Set to `blah` to do something.
-
-## Known Issues
-
-Calling out known issues can help limit users opening duplicate issues against your extension.
