In the case I want to fork a project from GitHub that has the LGPL3.0 or the GPL3.0 license, what do I have to do? The original license text might contain the "process" that is required (keep those files, change these files), but as I am not a lawyer, and English is not my first language, I do not understand what is written there.
I'd appreciate if someone could summarise what needs to be done exactly - in plain English - in the terms of the license, when I fork a GPL/LGPL project in GitHub.
