 Simple Tiling is a GNOME Shell extension created for users who want a clean, predictable, and automatic tiling layout without the complexity of larger, more feature-heavy tiling extensions. It is designed to be simple to configure and intuitive to use, focusing on a core set of essential tiling features.

 #### Manual Installation
 
-1. **Navigate to your extensions folder:**
+The repository includes a Makefile that produces ready‑to‑install ZIP packages for the two supported GNOME‑Shell lines (a legacy build (Gnome-Shell 3.38 - 44) and a modern build for Gnome-Shell 45+).
 
+1. **Clone the Source**
+```bash
+git clone https://github.com/YourUser/Simple-Tiling.git
+cd Simple-Tiling
+```
+
+2 · **Create the package that matches your GNOME-Shell version**
+   Open the Terminal within the Simple-Tiling directory and run
    ```bash
-   cd ~/.local/share/gnome-shell/extensions/
+   make build
    ```
-3. **Clone the repository directly into a folder named after the extension's UUID:**
+   **Note:** This will create a ready to go .zip archive of both, the modern and the legacy version of the extension ready to be used. Alternativley you can also run "make build-legacy" or "make build-modern" to only compile one of both versions.
 
-   ```bash
+3 · **Locate the output**
-   git clone https://github.com/Domoel/Simple-Tiling.git simple-tiling@domoel
+```bash
-   ```
+ls -1 ../simple-tiling@domoel-*-v*.zip
-5.  **Compile the GSettings schema.** This is a mandatory step for the keyboard shortcuts to work.
+```
+4 · **Install & enable**
+```bash
+gnome-extensions install ../simple-tiling@domoel-legacy-v6.zip
+gnome-extensions enable  simple-tiling@domoel
+```
+**Note:** You can also unzip the file and put the folder right into your extensions directory (~/.local/share/gnome-shell/extensions/)
 
-    ```bash
+5 · **Reload the shell**
-    cd ~/.local/share/gnome-shell/extensions/simple-tiling@domoel
+```bash
-    glib-compile-schemas schemas/
+Press Alt + F2, type  r , hit ↩   (works for X11 and Wayland)
-    ```
+```
-    
+6 · **Clean up (optional)**
-3.  **Restart GNOME Shell.** Press `Alt` + `F2`, type `r`, and press `Enter`.
+```bash
-   
+make clean        # removes build/ folder and generated ZIPs
-5.  **Enable the extension** using the GNOME Extensions app or GNOME Tweaks.
+```
 
 **Note:** You have to use "simple-tiling@domoel" as your extension folder / directory. Put all necessary files into this directory. Otherwise the extension will not show up in extension manager.

-* Support for newer Gnome shells
 * Additional layout algorithms.
 * A more detailed settings panel to configure other options via a GUI.
