+## README
+
+### Overview
+This tool provides two entry points: a CLI script (bal_wallet_utils.py) and a Qt GUI script (bal_wallet_utils_qt.py) that operate against an Electrum source tree.
+
+### Installation / Preparation
+1. Copy both files into the Electrum project root (the folder that contains the Electrum source package):
+   - bal_wallet_utils.py
+   - bal_wallet_utils_qt.py
+
+2. Activate the Electrum Python environment (the virtualenv used to run Electrum). Example (PowerShell, adjust path to your venv):
+```
+.\env\Scripts\Activate.ps1
+```
+or (cmd):
+```
+env\Scripts\activate.bat
+```
+
+### Running
+- CLI version:
+```
+python bal_wallet_utils.py
+```
+- Qt GUI version:
+```
+python bal_wallet_utils_qt.py
+```
+
+### Building a Windows executable with PyInstaller
+From the project root (with the Electrum environment active), you can build the Qt executable using PyInstaller. Example command (adjust the paths if your environment path differs):
+```
+pyinstaller.exe --onefile --noconsole --add-data "electrum\currencies.json;electrum" --add-data "electrum\bip39_wallet_formats.json;electrum" --add-data "electrum\lnwire\peer_wire.csv;electrum\lnwire" --add-data "electrum\lnwire\onion_wire.csv;electrum\lnwire" --add-binary "env/Lib/site-packages\electrum_ecc\libsecp256k1-6.dll;electrum_ecc" bal_wallet_utils_qt.py
+```
+
+Notes:
+- Run the command from the project root so relative paths resolve correctly.
+- On Windows the --add-data and --add-binary arguments use ";" to separate source and destination.
+- If electrum expects additional data files or native DLLs, include them with additional --add-data / --add-binary flags.
+- For debugging include --onedir first to inspect the created folder before using --onefile.
+
+### Troubleshooting
+- If PyInstaller is not found, run it via Python:
+```
+python -m PyInstaller <same arguments>
+```
+- If the frozen exe fails because DLLs or JSON files are missing, add those files explicitly with --add-data or --add-binary.
+- Test the build on a clean Windows VM to ensure all runtime dependencies are included.
