+
+Thanks for purchasing. To get started, I suggest trying out the various demo scenes.
+
+The documentation is shipped as a zip file in the same folder.
+Alternatively you can read the most up to date version of the documentation online here:
+https://oribow.github.io/PathBerserker2dDemo/Documentation/
+
+The documentation also includes guides on a variety of topics and explains the core concepts of this asset.
+
+As an extra treat, this Asset also comes with its complete source code, also as zip in this folder. 
+Setting your project up to use the source code instead of the DLL's requires some knowledge about C# projects.
+I recommend using the source code primarily as a reference guide.
+
+Happy path-finding!
