 You can install flawfinder a number of different ways.
 Choose the approach that's most convenient for you!

 For many, the simple approach is to first install Python
 (2.7 or something in the 3.* series). Then use "pip" to install flawfinder
 (this will normally download the package):
 
-  pip install flawfinder
+`pip install flawfinder`
 
 One advantage for using pip is that you'll generally get the
 *current* released version.
