Hacking 2ds Firmware 10.5.0-30e cfw help

[CrazyRach82]

I have a 2ds with the 10.5.0-30e. I want to install a custom firmware, but when it comes to doing this I'm an absolute noob.
I was looking at luma3ds, but I don't know if I can use that.
Do I have to downgrade first?
I've tried to look it up but I find it all very confusing
Any help would be appreciated.

What? 10.5? that's not an actual firmware... (EDIT: read it as 11.5, sorry)
well, if you want to have CFW you need to be at firmware 11.3 or lower and follow this guide
