 This tutorial explains how to create a ToolMap project manually. This approach has the following advantages:
 \begin{enumerate*}
-  \item It ensures the IDs used
-  \item It generates a multilingual model
+  \item It ensures that the ID remain consistent
+  \item It could generate a multilingual model
   \item It allows better monitoring of model changes
