+#### Windows first-time walkthrough
+
+If you are new to command-line tools, use this copy-and-paste path:
+
+1. Install Node.js 18 or newer, Git, and Claude Code.
+2. Open **PowerShell** from the Windows Start menu.
+3. Confirm that each prerequisite is available:
+
+   ```powershell
+   node --version
+   git --version
+   claude --version
+   ```
+
+4. Run the guided installer:
+
+   ```powershell
+   npx ecc-universal@2.2.2 setup
+   ```
+
+5. For a typical personal setup, choose **Global user**, choose **Standard** hooks, and confirm.
+6. Start a new Claude Code session and run `/plugin list` to verify that `ecc@ecc` is enabled.
+
+This path does not require cloning the repository. If any prerequisite command is not found, install or repair that prerequisite before rerunning ECC setup.
+
 If npm reports a version or cache error, confirm the registry version before retrying:
