Creating a Crypto / Forking Git & Building

[zb_classic]

I was wondering if there are any current / updated resources for creating a cryptocurrency / forking a git and building on top, or just plain direction on how to contribute. I've got a background in C++/Python and have followed crypto from an investor POV for several years but never took a stab at actually contributing.

I'm mainly interested in getting to know the environment better and have attempted a CryptoNote / CryptoNight build without success. I've got an EC2 loaded up but none of the packages are installing (assuming they're outdated now). Is there any detailed walkthrough for this material?

Thanks!
