Where to start with programming with the Ndless SDK?

Hi, I have the ndless sdk installed on my arch linux drive, and everything works functionally. I'm just looking for some beginner-friendly guides for writing some simple programs, and I would really appreciate it if you could point me towards some links. If possible, some example programs in C would be great too.
For the record, I've tried the documentation on hackspire but I couldn't find any of the basics on there.
Thanks
