 The Worlds First File Inflater
 
-Installation is simple, I don't feel the need for a makefile, but if you've no idea how to compile, just run:
-
-cc -o dpu ./dpu.c
-cc -o undpu ./undpu.c
+To build:
+`make`
 
 OR if you want to *install* it you can run:
-
-cc -o /usr/local/bin/dpu ./dpu.c
-cc -o /usr/local/bin/undpu ./undpu.c
+`make install`
 
 My further work will to be to properly use getopt (like not a chump), and also to create a proper useage()
 
 Right now, just use:
-dpu [decompression size] filename
+`dpu [decompression size] filename`
 
 The decompression size is an optional argument, and when used it will multiply the filesize by that. The default amount is 10 (making a file 10 times bigger).
