 **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.
+You'll need armips, [bin2c](https://sourceforge.net/projects/bin2c/), and a recent build of [makerom](https://github.com/profi200/Project_CTR) added to your PATH. [HERE](http://www91.zippyshare.com/v/ePGpjk9r/file.html) is a pre-compiled version of armips for Windows.  
+Then, just run "make" and everything should work!  
+You can find the compiled files in the 'out' folder.
 
-You also need to have a recent build of makerom in your path for the injector to be built.
+**Setup / Usage / Features:**
 
-Lastly, just run Make and everything should work!
-
-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://www77.zippyshare.com/v/oXDn2Hes/file.html).

 **Credits:**
  
-Rei as this is mostly his code.
-
-The offset to detect the console, and to calculate the O3DS NAND CTR are from Decrypt9.
-
-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, and the heavy revision to the reboot patch to allow for AGB/TWL loading are from CakesFW.
-
-ARM11 userland patching is only possible thanks to @yifanlu's 3ds_injector, which is bundled in the CFW.
