+Chatterbox TTS - Windows setup script
+
+What it does:
+- Creates a Python virtual environment in .venv (if missing)
+- Upgrades pip
+- Installs dependencies from backend/requirements.txt and requirements.txt
+- Creates a default .env with sensible ports if not present
+- Launches start_servers.py using the venv's Python
+
+Usage:
+  - Right-click this file and "Run with PowerShell" OR from PowerShell:
+      ./setup-windows.ps1
+  - Optional flags:
+      -NoInstall   -> Skip installing dependencies (just start servers)
+      -NoStart     -> Prepare env but do not start servers
+
+Notes:
+- You may need to allow script execution once:
+    Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser
+- Press Ctrl+C in the console to stop both servers.
