-# Setting Up Zoo Modeling App
-
-Compared to other CAD software, getting Zoo Modeling App up and running is quick and straightforward across platforms. It's about 100MB to download and is quick to install.
-
-## Windows
-
-1. Download the [Zoo Modeling App installer](https://zoo.dev/modeling-app/download) for Windows and for your processor type.
-
-2. Once downloaded, run the installer `Zoo Modeling App-{version}-{arch}-win.exe` which should take a few seconds.
-
-3. The installation happens at `C:\Program Files\Zoo Modeling App`. A shortcut in the start menu is also created so you can run the app easily by clicking on it.
-
-## macOS
-
-1. Download the [Zoo Modeling App installer](https://zoo.dev/modeling-app/download) for macOS and for your processor type.
-
-2. Once downloaded, open the disk image `Zoo Modeling App-{version}-{arch}-mac.dmg` and drag the applications to your `Applications` directory.
-
-3. You can then open your `Applications` directory and double-click on `Zoo Modeling App` to open.
-
-
-## Linux 
-
-1. Download the [Zoo Modeling App installer](https://zoo.dev/modeling-app/download) for Linux and for your processor type.
-
-2. Install the dependencies needed to run the [AppImage format](https://appimage.org/).
-    -  On Ubuntu, install the FUSE library with these commands in a terminal.
-       ```bash
-       sudo apt update
-       sudo apt install libfuse2
-       ```
-    - Optionally, follow [these steps](https://github.com/probonopd/go-appimage/blob/master/src/appimaged/README.md#initial-setup) to install `appimaged`. It is a daemon that makes interacting with AppImage files more seamless. 
-    - Once installed, copy the downloaded `Zoo Modeling App-{version}-{arch}-linux.AppImage` to the directory of your choice, for instance `~/Applications`.
-
-   - `appimaged` should automatically find it and make it executable. If not, run:
-     ```bash
-     chmod a+x ~/Applications/Zoo\ Modeling\ App-{version}-{arch}-linux.AppImage
-     ```
-
-3. You can double-click on the AppImage to run it, or in a terminal with this command:
-   ```bash
-    ~/Applications/Zoo\ Modeling\ App-{version}-{arch}-linux.AppImage
-   ```
