+Note: This is a draft list as of 9-Aug-19
+ - I dont believe "g_config.flying_limit.height_limit_enabled" works in FC Patcher. Instead, modify FLY_LIMIT_HEIGHT
+ - This needs to be broken out NFZ, height, speed, battery #TODO
+ - need to include Bret883's other parameters in this
+ - lets create a seperate wiki page for FC Patcher params #TODO

+Open dumldore v3, load firmware and flash it. You may need to hold down either ctrl or shift when clicking 'load firmware' to allow it to see this firmware file.
-The displayed percentage are fucked and it will go over 100% at some point, this is not an issue. You can monitor it from adb at the same time with : busybox tail -f /data/dji/log/upgrade00.log After a few seconds (10 ? 20 ?) you should hear the ESC beeping while the FC is being flashed (on Spark only) Then the bird will reboot (disconnecting you from adb if you were monitoring) 30-60 s after reboot you are good to turn the bird off, even if DUMLDore does not acknowledge a finished flash sequence (especially on Spark) The whole sequence is pretty short (less than 5 minutes)
+Few notes:
-Thats it your done.
+  * The displayed percentage will be wacky, it will go over 100% at some points
+  * If you want to view the update you can type
+   adb shell
+   busybox tail -f /data/dji/log/upgrade00.log
+  * You can also view in assistant, use 1.1.2
+  * After 10-20 seconds you should see the update go as regular; on Spark the ESC may beep while being updated.
+  * The aircraft will reboot in about a minute or so. If you were monitoring via adb, it will lose connection.
-For steps to get Galileo working see github
+Thats it you are done. The mods you modified in the flight parameters file will be in the aircraft. To reset, you will want to reinstall the firwmare using assistant or dumldore.
+Note: This mod also allows enabling Galileo GPS but I have not included steps on doing so. Please see Github original for additional help on setting this up.
+Remember, with great power comes great responsibility. Please don't use this tool set, guide or info to fly in restricted, dangerous or sensitive areas. Aka, don't be a dumbass when flying.
