 ### Linux and more than one controller with one Arduino
 Linux usbhid-module doesn't support out of box multiple controllers with one USB without USB-hub-features (I'm not sure about this). You have to give parameter 
-quirks=0x2341:0x8036:0x40 to usbhid-module. Here is example what to do with RetrOrangePi 2.5.2:
-0. Make backup of /boot/boot-retro.cmd and /boot/boot.scr
-1. Edit /boot/boot-retro.cmd setenv bootargs -line and add usbhid.quirks=0x2341:0x8036:0x40 to kernel parameters.
-2. sudo mkimage -C none -A arm -T script -d /boot/boot-retro.cmd /boot/boot.scr
+`quirks=0x2341:0x8036:0x40` to usbhid-module. Here is example how to do it with RetrOrangePi 2.5.2:
+- Make backup of `/boot/boot-retro.cmd` and `/boot/boot.scr`
+- Edit `/boot/boot-retro.cmd` setenv bootargs -line and add `usbhid.quirks=0x2341:0x8036:0x40` to kernel parameters.
+- `sudo mkimage -C none -A arm -T script -d /boot/boot-retro.cmd /boot/boot.scr`
 
 ### Code
 Select your controller by commenting and uncommenting stuff from beginning of source code and give your IO-pin numbers.
