 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 three supported Gnome‑Shell lines (a legacy build for Gnome-Shell 3.38, an enterprise build for Gnome-Shell 40, an interim build for Gnome-Shell 41 - 44 and a modern build for Gnome-Shell 45+).
 
+1. **Clone the Source**
    ```bash
-   cd ~/.local/share/gnome-shell/extensions/
+   git clone https://github.com/Domoel/Simple-Tiling.git
-   ```
+   cd Simple-Tiling
-3. **Clone the repository directly into a folder named after the extension's UUID:**
-
-   ```bash
-   git clone https://github.com/Domoel/Simple-Tiling.git simple-tiling@domoel
-   ```
-5.  **Compile the GSettings schema.** This is a mandatory step for the keyboard shortcuts to work.
-
-    ```bash
-    cd ~/.local/share/gnome-shell/extensions/simple-tiling@domoel
-    glib-compile-schemas schemas/
    ```
 
-3.  **Restart GNOME Shell.** Press `Alt` + `F2`, type `r`, and press `Enter`.
+2. **Install the package that matches your GNOME-Shell version**
 
-5.  **Enable the extension** using the GNOME Extensions app or GNOME Tweaks.
+   Open the Terminal within the Simple-Tiling directory and run
+   ```bash
+   make install-legacy        # Installs Legacy Extension (Gnome-Shell 3.38)
+   make install-enterprise    # Installs Enterprise Extension (Gnome-Shell 40)
+   make install-interim       # Installs Interim Extension (Gnome-Shell 41 - 44)
+   make install-modern        # Installs Modern Extension (Gnome-Shell 45+)
+   ```
+   **Note:** This command will directly install the extension in the choosen variant (legacy, interim or modern). If you want to manually create and upload the extension to your gnome extensions directory `(~/.local/share/gnome-shell/extensions)` you can just run `make build` to create all versions as .zip or `make build-legacy`, `make build-enterprise`, `make build-interim` or `make build-modern` to create them seperately as .zip. To enable them you need to unzip these archives and put them into your extensions directory.
 
-**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.
+4.  **Reload the shell**
+    ```bash
+    Press Alt + F2, type  r , hit ↩   (works for X11 and Wayland)
+    ```
+5.  **Clean up (optional)**
+    ```bash
+    make clean        # perform this command in the downloaded folder to remove builds and generated ZIPs
