# Installation Notes:
# ==================
# 
# For Python 3.13+ (Kali Linux, newer distributions):
# - The installer will automatically create a virtual environment
# - This avoids externally-managed-environment errors
# - System packages (python3-dnspython) are preferred when available
#
# For older Python versions:
# - Direct installation via pip should work normally
# - Virtual environments are still recommended for isolation
#
# System package alternatives:
# - Debian/Ubuntu/Kali: sudo apt install python3-dnspython
# - Fedora: sudo dnf install python3-dns
# - Arch: sudo pacman -S python-dnspython
#
# Manual installation fallback:
# - pip3 install --user dnspython (user-local)
# - pip3 install --user --break-system-packages dnspython (override)
#
# Virtual environment installation:
# - python3 -m venv ~/.est-env
# - source ~/.est-env/bin/activate
# - pip install -r requirements.txt
