How does the Arduino library work?

Question

Arduino

Help me understand how the Arduino library works, I'm talking about descriptions of functions from the library, where to get something to make it all work
. I have a library for DS3231, but it doesn't work, the whole point is that the module is the same and there are 100 libraries, and everyone is different

Answer 1

1. Get rid of Russian characters on the way.
2. Get rid of library copies.
And in general, since there is no knowledge, it is better to use the built-in package manager
