+# muscript README
+
+This is the README for your extension "muscript". After writing up a brief description, we recommend including the following sections.
+
+## 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.
+
+## Release Notes
+
+Users appreciate release notes as you update your extension.
+
+### 1.0.0

+Initial release of ...
+
+### 1.0.1

+
+## Working with Markdown
+
+You can author your README using Visual Studio Code. Here are some useful editor keyboard shortcuts:
+
+* Split the editor (`Cmd+\` on macOS or `Ctrl+\` on Windows and Linux).
+* Toggle preview (`Shift+Cmd+V` on macOS or `Shift+Ctrl+V` on Windows and Linux).
+* Press `Ctrl+Space` (Windows, Linux, macOS) to see a list of Markdown snippets.
+
+## For more information
