Probably posted before but is there a beginners guide/pdf on how to install Ndless to both my TI-Nspire CX CAS and my TI-Nspire Touchpad. Also are there any good PDFs or tutorials on using Ndless as I’m a complete novice but Pure Mathematician? My CX-CAS is on OS 4.5.0.1180 and the Touchpad is OS 3.9.0.463
