 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.

-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+).
+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. **Clone the Source**
-```bash
-git clone https://github.com/YourUser/Simple-Tiling.git
-cd Simple-Tiling
-```
+   ```bash
+   git clone https://github.com/Domoel/Simple-Tiling.git
+   cd Simple-Tiling
+   ```
+
+2. **Install the package that matches your GNOME-Shell version**
 
-2 · **Create the package that matches your GNOME-Shell version**
    Open the Terminal within the Simple-Tiling directory and run
    ```bash
-   make build
+   make install-legacy        # Installs Legacy Extension (Gnome-Shell 3.38)
+   make install-interim       # Installs Interim Extension (Gnome-Shell 40 - 44)
+   make install-modern        # Installs Modern Extension (Gnome-Shell 45+)
    ```
-   **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.
+   **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.
