 **Compiling:**
 
-You'll need armips and [bin2c](https://sourceforge.net/projects/bin2c/) added to your Path. [HERE](http://www91.zippyshare.com/v/ePGpjk9r/file.html) is a pre-compiled version of armips.
+First you need to clone the repository recursively with: 'git clone --recursive https://github.com/AuroraWright/Luma3DS.git'  
+To compile, you'll need [armips](https://github.com/Kingcom/armips), [bin2c](https://sourceforge.net/projects/bin2c/), and a recent build of [makerom](https://github.com/profi200/Project_CTR) added to your PATH.  
+For your convenience, here are [Windows](http://www91.zippyshare.com/v/ePGpjk9r/file.html) and [Linux](https://mega.nz/#!uQ1T1IAD!Q91O0e12LXKiaXh_YjXD3D5m8_W3FuMI-hEa6KVMRDQ) builds of armips (thanks to who compiled them!).  
+Finally just run 'make' and everything should work!  
+You can find the compiled files in the 'out' folder.
 
-Lastly, just run Make and everything should work!
+**Setup / Usage / Features:**
 
-Copy everything in 'out' folder to SD root and run!
-
-**Usage / Features:**
-
-See https://github.com/Reisyukaku/ReiNand and http://gbatemp.net/threads/reinand-mod-o3ds-n3ds-sysnand.411110
-
-The FIRMs you need are [HERE](http://www99.zippyshare.com/v/kEIiQl0x/file.html).
+See https://github.com/AuroraWright/Luma3DS/wiki
 
 **Credits:**
  
-Rei as this is mostly his code.
+See https://github.com/AuroraWright/Luma3DS/wiki/Credits
 
-The offset to detect the console, and to calculate the O3DS NAND CTR are from Decrypt9.
+**Licensing:**
 
-tiniVi suggested me a way to detect a A9LH environment, and figured out screen deinit.
-
-Delebile provided me with the FIRM writes blocking patch.
-
-A skilled reverser gave me the new reboot patch.
-
-The screen init code is from dark_samus, bil1s, Normmatt, delebile and everyone who contributed.
-
-The code for printing to the screen is from CakesFW.

+/* The option _FS_REENTRANT switches the re-entrancy (thread safe) of the FatFs
+/  module itself. Note that regardless of this option, file access to different
+/  volume is always re-entrant and volume control functions, f_mount(), f_mkfs()
+/  and f_fdisk() function, are always not re-entrant. Only file/directory access
+/  to the same volume is under control of this function.
+/
+/   0: Disable re-entrancy. _FS_TIMEOUT and _SYNC_t have no effect.
+/   1: Enable re-entrancy. Also user provided synchronization handlers,
+/      ff_req_grant(), ff_rel_grant(), ff_del_syncobj() and ff_cre_syncobj()
+/      function, must be added to the project. Samples are available in
+/      option/syscall.c.
+/
+/  The _FS_TIMEOUT defines timeout period in unit of time tick.
+/  The _SYNC_t defines O/S dependent sync object type. e.g. HANDLE, ID, OS_EVENT*,
+/  SemaphoreHandle_t and etc.. A header file for O/S definitions needs to be
+/  included somewhere in the scope of ff.c. */
