-==== Compiling the Source ====
+==== Compilation ====
 === Prerequisites ===
   * A MPI compiler, e.g. OpenMPI or MPICH.
   * CUDA Toolkit
 === Compilation ===
+Short version:
 <code bash>
-cd USER-MESO
+$ cd USER-MESO
-make clean-all     # delete temporary files if any was left from last compilation
+$ make clean-all     # delete temporary files if any was left from last compilation
-make yes-molecule  # dependency
+$ make yes-molecule  # dependency
-make yes-user-meso # configure the USER-MESO package
+$ make yes-user-meso # configure the USER-MESO package
-make meso
+$ make meso
 </code>
+Long Version:
+First, make sure that mpic++ and nvcc are available by
+<code bash>
+$ which mpic++
+$ which nvcc
+</code>
+You should be expecting output that looks like
+<code bash>
+$ which mpic++
+/usr/lib64/mpich/bin/mpic++
+$ which nvcc
+/usr/local/cuda/bin/nvcc
+</code>
+If you are sure that MPI and CUDA are present, but still get messages like
+<code bash>
+/usr/bin/which: no mpic++ in (/usr/local/bin:/bin:/usr/bin)
+</code>
+Then adjust **''Makefile.meso''** located in **''USER-MESO/MAKE''** by setting the **''CC''** and **''MPICXX''** environment variables to be the absolute path to nvcc and mpic++, respectively.
