Please Add Image Size to Menu

While installing Nethunter I ran into an impasse. I need to chose the image size: Full, Minimal, or Nano. . .while descriptive they don't tell me what I need to know. I only have 2 GB of system space left on this old jalopy and I obviously want the most complete experience possible, and for the life of me I haven't been able to find their sizes. Guess I gotta pull the trigger blindly and hope I'm not wasting my time. But I'm super stoked to give Kali a go. And super job on everything so far 👍
