 ## Introduction
 
 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.

 * **Interactive Window Swapping:**
     * **Drag & Drop:** Swap any two windows by simply dragging one and dropping it over the other.
     * **Keyboard Shortcuts:** A full set of keyboard shortcuts allows you to swap the focused window with the master or with its nearest neighbor in any direction (left, right, up, down).
-* **Interactive Window Focus Switcher:** Change the current window focus with a set of customizable keyboard shortcuts in every direction.

+* **Simple Settings Panel:** A simple settings panel within the gnome extension manager menu to adjust key bindings, window gaps / margins and window behavior.
 * **External Exception List:** Use a simple `exceptions.txt` file to list applications (by their `WM_CLASS`) that should be ignored by the tiling manager.
 * **Smart Pop-up Handling:** Windows on the exception list, as well as dialogs and other pop-ups, are automatically centered and kept "always on top" for a smooth workflow.
 * **Configurable Tiling Window Delays:** Easily configure the tiling window delays if you have race condition issues by editing variables directly in the `extension.js`.

 ## Installation
@@ -50,23 +49,48 @@ Use the [GNOME Shell Extensions website](https://extensions.gnome.org/extension/
 
 #### Manual Installation
 
-1.  **Clone the repository** into your local extensions directory:
+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/Domoel/Simple-Tiling.git
+git clone https://github.com/YourUser/Simple-Tiling.git
+cd Simple-Tiling
 ```
-2.  **Compile the GSettings schema.** This is a mandatory step for the keyboard shortcuts to work.
+
+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/simple-tiling@domoel/
-    glib-compile-schemas schemas/
+   make build
    ```
-3.  **Restart GNOME Shell.** Press `Alt` + `F2`, type `r`, and press `Enter`.
-4.  **Enable the extension** using the GNOME Extensions app or GNOME Tweaks.
+   **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.
+
+3 · **Locate the output**
+```bash
+ls -1 ../simple-tiling@domoel-*-v*.zip
+```
+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/)
+
+5 · **Reload the shell**
+```bash
+Press Alt + F2, type  r , hit ↩   (works for X11 and Wayland)
+```
+6 · **Clean up (optional)**
+```bash
+make clean        # removes build/ folder and generated ZIPs
+```
+
+**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.
