 To compile with TBB on Cray systems, load the intel module, which will automatically configure the environment.

+The guide below shows how to use the version of TBB that is installed as part of the Intel compiler tool-chain.
 It is recommended that you install the most recent version of TBB yourself, and link against this, because older versions
 of TBB don't work with recent versions of GCC.

 The source to source compiler "modparser" that generates the C++/CUDA kernels for the ion channels and synapses is in a separate repository.
-It is included in our project as a git submodule, and by default it will be built with the same compiler and flags that are used to build the miniapp and tests.
+By default it will be built with the same compiler and flags that are used to build the miniapp and tests.
 
 This can cause problems if we are cross compiling, e.g. for KNL, because the modparser compiler might not be runnable on the compilation node.
-CMake will look for the source to source compiler executable, `modcc`, in the `PATH` environment variable, and will use the version if finds instead of building its own.
+You are probably best of building the software twice: Once without KNL support to create the modcc parser and next the KNL version using
+the now compiled executable
 
 Modparser requires a C++11 compiler, and has been tested on GCC, Intel, and Clang compilers
   - if the default compiler on your is some ancient version of gcc you might need to load a module/set the CC and CXX environment variables.
 
-```bash
-git clone git@github.com:eth-cscs/modparser.git
-cd modparser
-
-# example of setting a C++11 compiler
-export CXX=`which gcc-4.8`
 
-cmake .
-make -j
