+# Script: run_devcontainer_claude_code.ps1
+# Author: [Your Name or Project Name]
+# Description: Automates the setup and connection to a DevContainer environment
+#              using either Docker or Podman on Windows.
+#
+# IMPORTANT USAGE REQUIREMENT:
+# This script MUST be executed from the ROOT directory of your project.
+# It assumes the script file itself is located in a 'Script' subdirectory.
+#
+# Assumed Project Structure:
+# Project/
+# ├── .devcontainer/
+# └── Script/
+#     └── run_devcontainer_claude_code.ps1  <-- This script's location
+#
+# How to Run:
+# 1. Open PowerShell.
+# 2. Change your current directory to the project root:
+#    cd c:\path\to\your\Project
+# 3. Execute the script, specifying the container backend:
+#    .\Script\run_devcontainer_claude_code.ps1 -Backend <docker|podman>
+#
+# The -Backend parameter is mandatory and accepts 'docker' or 'podman'.
