 \section{MontiumC}
-This section will describe MontiumC and the montium programming workflow.
+Since having just a piece of hardware is not enough, we also need some way to
+program the Montium. To this end, the MontiumC language was created. The
+MontiumC language is a language very similar to C. It allows very fine grained
+control over the montium through a set of functions that can be called (where
+the function called determines the operation mapped on the montium).
+
+MontiumC is, on one hand, a strict subset of C. Every MontiumC program is
+therefore a valid C program as well. This is one of the strong points of
+MontiumC: By using a normal C compiler, a MontiumC program can be functionally
+simulated on normal hardware.
+
+Figure \ref{CompilingMontiumC} show the flow for compiling a MontiumC program
+into a Montium binary file, which can be loaded directly onto a Montium. The
+process is roughly divided into two parts (each of which corresponds to a
+different program in the compiler suite): The frontend and the backend.
+
+The frontend takes in a MontiumC program and turns it into a lower level
+description of the program. The frontend is responsible for mapping higher level
+C constructs onto simpler instructions, for canonicalizing and simplifying the
+code. These canonicalizations and simplifications ensure that the backend can be
+kept simpler and does not have to deal with all the complexities of the original
+program. 
+
+The frontend is again divided into two pieces, the first of which
+transforms C code into an intermediate representation (also see section
+\ref{LLVM}). The second part transforms this intermediate representation, output
+again a (reduced form of) this representation.
+
+The backend, in turn, takes in this reduced description of the program and
+transforms this into a valid Montium binary. To do this, it must find an ALU
+configuration to execute a given set of operations, trace values to allocate
+them to registers, generate instructions for the adress generation units, etc.
