# MeshCore GUI — Serial Installer
|
||||
# ============================================================================
|
||||
#
|
||||
# Installs a systemd service for the serial-based MeshCore GUI.
|
||||
# Automatically detects paths and the current user.
|
||||
#
|
||||
# Usage:
|
||||
# bash install_scripts/install_serial.sh # from project root
|
||||
# cd install_scripts && bash install_serial.sh # from install_scripts/
|
||||
#
|
||||
# Optional:
|
||||
# bash install_scripts/install_serial.sh --uninstall
|
||||
#
|
||||
# Requirements:
|
||||
# - meshcore-gui project with venv/ directory
|
||||
# - sudo access (for systemd)
