-  \item VDMJ uses Java, meaning the logical choice would be to use something with Java
-  \item As the tester is going to include a UI, the language choice was still important
+  \item There are multiple langauges that are made for or support JVMs~\cite{jvm-alt-lang}
+  \item Requirements for language
+    \begin{itemize}
+      \item Be able to interact with Java code because of VDMJ
+      \item Have Graphical User Interface (GUI) libraries
+      \item Have good support (the more popular, the more resources available)
+    \end{itemize}
+  \item The main contenders were Java and Kotlin~\cite{kotlin}
   \item Kotlin~\cite{kotlin} was the choice in the end as Google has been putting Kotlin first
-    compared to Java, it includes less boilerplate code (e.g. getters and setters)~\cite{android-kotlin}
-  \item There are a variety of GUI libraries to consider using
