+  \section{Prototype implementation}
+    The prototype has been implemented using Haskell as its
+    implementation language, just like \GHC. This allows the prototype
+    do directly use parts of \GHC\ through the \small{API} it exposes
+    (which essentially taps directly into the internals of \GHC, making
+    this \small{API} not really a stable interface).
+
+    Cλash can be run from a separate library, but has also been
+    integrated into \type{ghci} \cite[baaij09]. The latter does requires
+    a custom \GHC\ build, however.
+
+    The latest version and all history of the Cλash code can be browsed
+    online or retrieved using the \type{git} program.
