 Ensure the following software are installed: Make, CMake, GCC, and Git.  To setup the cFS BUNDLE directly from the latest set of interoperable repositories:
 
+```bash
     git clone https://github.com/nasa/cFS.git
     cd cFS
     git submodule init
     git submodule update
+```
 
 Copy in the default makefile and definitions:
 
+```bash
     cp cfe/cmake/Makefile.sample Makefile
     cp -r cfe/cmake/sample_defs sample_defs
+```
 
 ## Build and Run
 
 The cFS Framework including sample applications will build and run on the pc-linux platform support package (should run on most Linux distributions), via the steps described in https://github.com/nasa/cFE/tree/master/cmake/README.md.  Quick-start is below:
 
 To prep, compile, and run on the host (from cFS directory above) as a normal user (best effort message queue depth and task priorities):
 
+```bash
     make SIMULATION=native prep
     make
     make install
     cd build/exe/cpu1/
     ./core-cpu1
+```
 
 Should see startup messages, and CFE_ES_Main entering OPERATIONAL state.  Note the code must be executed from the build/exe/cpu1 directory to find the startup script and shared objects.
