+# acmhelper-vscode README
+
+This is the README for your extension "acmhelper-vscode". 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
+
+Fixed issue #.
+
+### 1.1.0
+
+Added features X, Y, and Z.
+
+-----------------------------------------------------------------------------------------------------------
+
+## Working with Markdown
+
+**Note:** 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) or `Cmd+Space` (macOS) to see a list of Markdown snippets
+
+### For more information

+# Welcome to your VS Code Extension
+
+## What's in the folder
+* This folder contains all of the files necessary for your extension.
+* `package.json` - this is the manifest file in which you declare your extension and command.
+The sample plugin registers a command and defines its title and command name. With this information
+VS Code can show the command in the command palette. It doesn’t yet need to load the plugin.
+* `src/extension.ts` - this is the main file where you will provide the implementation of your command.
+The file exports one function, `activate`, which is called the very first time your extension is
+activated (in this case by executing the command). Inside the `activate` function we call `registerCommand`.
+We pass the function containing the implementation of the command as the second parameter to
+`registerCommand`.
+
+## Get up and running straight away
+* Press `F5` to open a new window with your extension loaded.
+* Run your command from the command palette by pressing (`Ctrl+Shift+P` or `Cmd+Shift+P` on Mac) and typing `Hello World`.
+* Set breakpoints in your code inside `src/extension.ts` to debug your extension.
+* Find output from your extension in the debug console.
+
+## Make changes
+* You can relaunch the extension from the debug toolbar after changing code in `src/extension.ts`.
+* You can also reload (`Ctrl+R` or `Cmd+R` on Mac) the VS Code window with your extension to load your changes.
+
+## Explore the API
+* You can open the full set of our API when you open the file `node_modules/vscode/vscode.d.ts`.
+
+## Run tests
+* Open the debug viewlet (`Ctrl+Shift+D` or `Cmd+Shift+D` on Mac) and from the launch configuration dropdown pick `Extension Tests`.
+* Press `F5` to run the tests in a new window with your extension loaded.
+* See the output of the test result in the debug console.
+* Make changes to `test/extension.test.ts` or create new test files inside the `test` folder.
+    * By convention, the test runner will only consider files matching the name pattern `**.test.ts`.
+    * You can create folders inside the `test` folder to structure your tests any way you want.
