+# GNOME Terminal Auto Theme Sync
+
+![GNOME Terminal Logo](https://upload.wikimedia.org/wikipedia/commons/d/da/GNOME_Terminal_icon_2019.svg)
+
+Automatically sync your GNOME Terminal theme with your system's light/dark mode preferences.
+
+## Features
+
+- 🌓 Automatic theme switching between light and dark modes
+- ⚡ Instant theme application when system preference changes
+- 🔄 Background process that monitors system theme changes
+- 🛠️ Easy installation and uninstallation
+
+## Installation
+
+1. **Download the project files**:
+
+```bash
+git clone https://github.com/MatMasIt/gnome-terminal-autotheme.git
+cd gnome-terminal-autotheme
+```
+
+2. **Run the installer**:
+
+```bash
+./install.sh
+```
+
+3. **Follow the prompts** to complete installation.
+
+The installer will:
+- Copy necessary files
+- Set up autostart entry
+- Start the theme sync service
+
+## Uninstallation
+
+To remove the auto theme sync, simply run the installer again.
+
+You'll be prompted to choose:
+- Remove just the autostart entry or the whole installation
+- Whether to keep your terminal in light or dark mode after uninstall
+
+## Requirements
+
+- GNOME Desktop Environment (tested on GNOME 40+)
+- GNOME Terminal
+- Bash 4.0+
+
+## Configuration
+
