 I was bored on an aeroplane so I decided to re-write Tony Monroe's cowsay in C. 
 It does not support multiple cow types or changing the features of the cow, but 
-after several more hours of lazy printf debugging it does wrap text in an almost-
-identical way.

+
+## Build Instructions
+
+`sudo make install` will build and install it, overriding an original cowsay binary. 
+To avoid this, use `sudo make install-compat` which will install it as `ccowsay`.
+
+Just `make` or `make debug` will just build the binary without, or with debug flags 
+respectively.
