 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.

-* **GNOME Shell Version:** **3.38 - 49**

-* **Session Type:** **X11** (Wayland is still in beta but should be fine!).

 #### Manual Installation
 
-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 interim build for Gnome-Shell 40 - 44 and a modern build for Gnome-Shell 45+).
+1. **Navigate to your extensions folder:**
 
-1. **Clone the Source**
    ```bash
-   git clone https://github.com/Domoel/Simple-Tiling.git
+   cd ~/.local/share/gnome-shell/extensions/
-   cd Simple-Tiling
    ```
+3. **Clone the repository directly into a folder named after the extension's UUID:**
 
-2. **Install the package that matches your GNOME-Shell version**
-
-   Open the Terminal within the Simple-Tiling directory and run
    ```bash
-   make install-legacy        # Installs Legacy Extension (Gnome-Shell 3.38)
+   git clone https://github.com/Domoel/Simple-Tiling.git simple-tiling@domoel
-   make install-interim       # Installs Interim Extension (Gnome-Shell 40 - 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-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.
+5.  **Compile the GSettings schema.** This is a mandatory step for the keyboard shortcuts to work.
 
-4.  **Reload the shell**
     ```bash
-    Press Alt + F2, type  r , hit ↩   (works for X11 and Wayland)
+    cd ~/.local/share/gnome-shell/extensions/simple-tiling@domoel
-    ```
+    glib-compile-schemas schemas/
-5.  **Clean up (optional)**
-    ```bash
-    make clean        # perform this command in the downloaded folder to remove builds and generated ZIPs
     ```
     
+3.  **Restart GNOME Shell.** Press `Alt` + `F2`, type `r`, and press `Enter`.
+   
+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.
