-### Building from source using the Unreal Engine Editor and Ubuntu 20.04,22.04+
-This guide outlines the steps for building the project from source on Ubuntu 20.04 and 22.04. It should also work for Ubuntu 24.04+, although this has not yet been tested.
+### From source using the Unreal Engine Editor
+Instead of running the simulator from release binaries, you can compile it manually using unreal engine.
+This is usefull if you want to get the latest changes or if you want to make changes to the maps or the simulation itself.
+If you want to run the unreal engine project from source you will need [unreal engine and visual studio 2019](software-install-instructions.md).
+On Ubuntu you can skip the visual studio 2019 part, but you still need Unreal Engine.

+#### 1. Get the repository
+
+You can either download the repo using the big green download button on the [github page of this project](https://github.com/FS-Driverless/Formula-Student-Driverless-Simulator) or clone the repository. For cloning, checkout the documentation on this further down this page. Make sure you clone the repository in your **home directory** and git **submodules** are included:
+
+```
+git clone https://github.com/FS-Driverless/Formula-Student-Driverless-Simulator.git --recurse-submodules
+```
+
+When downloading or cloning, by default you get the latest, unreleased version. This is probably not the version that you want. Make sure you select the version that you need! 
 
-#### Build AirSim
-##### For Ubuntu 20.04
+#### 2. Compiling the AirSim plugin
+The Unreal Engine project requires the AirSim plugin.
+We have to compile this plugin first.
+The AirSim plugin is made up of AirLib (/AirSim/AirLib) and the plugin code (/UE4Project/Plugins/AirSim/Source).
+AirLib is the shared code between the ros wrapper and the AirSim Unreal Engine plugin.
+
+First build the AirLib code.
 
-    cd /home/$USER/Formula-Student-Driverless-Simulator/AirSim
-    ./setup.sh && ./build.sh
+On Windows, open the _Developer Command Prompt for VS 2019_, go to `Formula-Student-Driverless-Simulator/AirSim` and run
+```
+build.cmd
+```
+
+On Ubuntu 18.04 and 20.04, go to folder `AirSim` and run `setup.sh` and `build.sh`.
 
 ##### For Ubuntu 22.04+

 First, install Docker on your Ubuntu system.

 > So what does build.cmd or setup.sh+build.sh do? 
   It downloads any nessesary libraries and compiles AirLib.
