 The file will be written to a place of your choice on your SD card. At the moment, most places to choose from are in in the [Luma3DS](https://github.com/AuroraWright/Luma3DS) payloads folder.
 __Developers please contact me if you need A9NC to write to a different location__. 
 
-To use the chainloader, you need to move your default payload (usually your CFW) at `/A9NC/payload.bin` and copy the chainloader payload to either `arm9loaderhax_si.bin` or `arm9loaderhax.bin`. Typically, `arm9loaderhax_si.bin` will be the right choice, because screen init is not implemented yet.
+Requires devKitARM, libctru and zlib to compile. For easy zlib installation [go here](https://github.com/devkitPro/3ds_portlibs).

+## Sighax instructions

+Use [SafeB9SInstaller](https://github.com/d0k3/SafeB9SInstaller/releases) to install alternative boot9strap [from here](https://github.com/d0k3/boot9strap). A9NC can write to `/bootonce.bin`, which is loaded one time, then deleted from the SD card.

+## A9LH chainloader instructions
+
+The chainloader onyl works on arm9loaderhax at the time of writing. To use the chainloader, you need to move your default payload (usually your CFW) at `/A9NC/payload.bin` and copy the chainloader payload to either `arm9loaderhax_si.bin` or `arm9loaderhax.bin`. Typically, `arm9loaderhax_si.bin` will be the right choice, because screen init is not implemented yet.
 
 Todo for the chainloader:
   * Adding in screen init
   * Confirm compatibility for all CFW (only tested on Luma at the time of writing, it most likely include Reinand and Luma's forks such as Puma)
