+\section{Unreal engine environment setup}
+    In this section, the setup of the Unreal Engine Environment is described.
+
+    This guide expects the Unreal Engine to run on a Windows machine.
+
+    \subsection{Unreal engine}
+        First, the \href{https://www.unrealengine.com/en-US/download}{Epic Games Launcher} must be installed.
+        To be able to install the Unreal Engine, a epic account must be created.
+
+        Then, the Unreal Engine itself is installed.
+        It is important to mention, when the \href{https://www.unrealengine.com/marketplace/en-US/product/city-sample}{City Sample} is planned to be used,
+        Unreal Engine 5.2.x (the latest version supported by Colosseum at the time writing this guide) has a severe bug in rendering the meshes of pedestrians
+        and traffic leading to crashes of the environment.
+        Therefore, when the City Sample is planned to be used, it is important to use Unreal Engine 5.1.x.
+
+        Now, the Unreal Engine can be installed.
