 =========
 
 So let's say you want to access an i2c adapter from a C program. The
-first thing to do is `#include <linux/i2c.h>" and "#include <linux/i2c-dev.h>. 
-Yes, I know, you should never include kernel header files, but until glibc

+first thing to do is "#include <linux/i2c-dev.h>". Please note that
+there are two files named "i2c-dev.h" out there, one is distributed
