 ## Installation & Running
 
-### Option 1: Run via Docker (Recommended)
-Avoid system dependency issues (missing X11/GL headers) by running the app in a container.
-
-```bash
-./docker-run.sh
-```
-*The app will appear on your desktop via X11 forwarding.*
-
-### Option 2: Run Locally (Linux)
-Requires `gcc`, `libgl1-mesa-dev`, and `xorg-dev`.
+### Run via Script (Linux)
+This script handles dependency checks and runs the application.
 
 ```bash
-sudo apt-get install libgl1-mesa-dev xorg-dev
 ./run.sh
 ```
+*Note: You may need to install `gcc`, `libgl1-mesa-dev`, and `xorg-dev` if prompted.*
 
-### Option 3: Build Binaries
+### Build Binaries
 To generate standalone executables for Linux and Windows:
 
 ```bash
 ./build.sh
 ```
 *Artifacts will be created as `dback-linux` and `dback-windows.exe`.*
 
+### Docker Alternative
+If you have issues with system dependencies, you can run the app in a container:
+
+```bash
+./docker-run.sh
+```

 ## FAQ
 
 ### Why does this app require X11/GL libraries?
-This application is built using **Fyne**, a high-performance GUI toolkit for Go. Fyne uses **OpenGL** to render its graphics (GPU acceleration). On Linux, interfacing with OpenGL and creating windows requires the **X11** and **OpenGL** development headers. Using the Docker method (`./docker-run.sh`) bypasses this requirement on your host machine.
