 This library implements an embedded filesystem mountpoint for usage with devkitPPC aimed at the Nintendo Wii U. The implementations works by statically linking the romfs directory compressed with ustar to the executable.
 
 ### Usage

 Include library's header: `#include <romfs-wiiu.h>`
-Call `romfsInit()` at the start of you app and `romfsExit()` before exiting

+#### Makefile
 To generate the romfs, define a ROMFS variable in you makefile containing the path of your romfs folder:
 
     ROMFS := romfs_example_folder
+
 Then, include romfs's makefile and add romfs target to your linking targets along with the ld flags (chage the example according to your makefile):
 
     include $(PORTLIBS_PATH)/wiiu/share/romfs-wiiu.mk
