   *  Choose your model file
   *  Choose a target directory for the generated source code (`"<fUML-C#-rootdir>\fUML-CSharp\usersrc\<model-name>"` is suggested)
 * Open newly generated C# project in Visual Studio and build executable(s)
+* **NOTE**: Depending on the target directory path it might be necessary to adapt the project's dependencies to the *uml*, *fuml* and *pscs* assemblies since they are referenced by relative paths. This only applies if you choose a target directory structure that differes from the one suggested above.
 * Run executable from command line using `<executable-name> <behavior-name> [<behavior-name> <behavior-name> <behavior-name> <...>]`
