-# ------------------------------------
-# Python dependencies for this project
-# ------------------------------------
-# This project only uses Python's standard library modules:
-#   - json
-#   - subprocess
-#   - os
-#   - tkinter (comes bundled with Python on most systems)
-#
-# Therefore, there are no external Python packages needed
-# to be installed via pip.
-#
-# You do, however, need "scrcpy" and "adb" installed on your system PATH.
-#
-# If you are missing tkinter (rare on some systems), you may need to install:
-#   - On Debian/Ubuntu: sudo apt-get install python3-tk
-#   - On macOS (Homebrew): brew install python-tk (usually tkinter is pre-included)
-#   - On Windows: usually included with official Python installer
+# Requirements for ADB Unlock, Screenshot & Scrcpy Tool
+
+# Python dependencies:
+# - tkinterdnd2 (external package for drag-and-drop support)
+tkinterdnd2
+
+# The rest of the required software is non-Python:
+# 1. Android Debug Bridge (ADB)
+#    - Download from: https://developer.android.com/studio/releases/platform-tools
+# 2. Scrcpy
+#    - Installation guide: https://github.com/Genymobile/scrcpy
+
+# Note: If tkinter is missing (rare):
+# - On Debian/Ubuntu: sudo apt-get install python3-tk
+# - On macOS (Homebrew): brew install python-tk
+# - On Windows: Included in the Python installer
