 # Developing
 
 ## Requirements
-- **Node.js 22.14.0 or higher** (see [Node Version](#node-version-management) below)
-- **npm 9.0.0 or higher**
+- Node 22.x
 - Python >= 3.10, <= 3.12
 - Git Large File Storage (LFS) - for running tests
 - (Windows) Visual Studio Build Tools >=2019 - for building with node-gyp [see node-gyp docs](https://github.com/nodejs/node-gyp?tab=readme-ov-file#on-windows)
 
-### Node Version Management
-
-This project requires Node.js 22.14.0 or higher. The exact version used by the project is specified in `.nvmrc`.
-
-**Using Node Version Manager (nvm) - Recommended:**
-```bash
-# Install and use the correct Node.js version
-nvm install 22.15.1
-nvm use 22.15.1
-
-# Verify version
-node --version  # should show v22.15.1 or higher
-```
-
-**Manual Installation:**
-Download Node.js 22.x from [nodejs.org](https://nodejs.org/) if you prefer not to use nvm.
-
-### Copilot Agent Environment Setup
-
-This extension works with GitHub Copilot agents and requires proper authentication and environment configuration. Follow these steps for agent environment customization:
-
-1. **GitHub Authentication**: Ensure you have access to GitHub Copilot
-2. **Development Token**: Run `npm run get_token` to set up your development OAuth token
-3. **Environment Variables**: Run `npm run get_env` to configure additional secrets (for Microsoft team members)
-
-For more details on customizing the Copilot agent environment, see the [GitHub Copilot documentation](https://docs.github.com/en/copilot/how-tos/use-copilot-agents/coding-agent/customize-the-agent-environment).
-
 ### First-time setup
-1. **Check Prerequisites**: Verify your development environment meets the requirements
-   ```bash
-   # Check Node.js and npm versions
-   npm run check-env
-   ```
-
-2. **Windows Setup**: On Windows, run `Set-ExecutionPolicy Unrestricted` as admin in Powershell.
-
-3. **Install Dependencies**: 
-   ```bash
-   npm install
-   ```
-
-4. **Authentication Setup**:
-   ```bash
-   # Set up GitHub OAuth token for development
-   npm run get_token
-   
-   # (Microsoft team members only) Set up additional environment variables
-   npm run get_env
-   ```
-
-5. **Start Development**: 
-   - Use VS Code's build task: `Ctrl+Shift+P` → "Tasks: Run Build Task" 
-   - Or start the "Launch Copilot Extension - Watch Mode" launch config to build and debug the extension
+- on Windows you need to run `Set-ExecutionPolicy Unrestricted` as admin in Powershell.
+- `npm install`
+- `npm run get_token`
+- Then you can run the build task with `cmd+shift+B`, or just start the "Launch Copilot Extension - Watch Mode" launch config to start the build then start debugging the extension.
 
 **Tip:** If "Launch Copilot Extension - Watch Mode" doesn't work for you, try using the "Launch Copilot Extension" debug configuration instead.
