Where to find Golang package functions?

Question

go

Hello. I just started to understand Go.
Can you please tell me where to find all the functions of all packages of the standard library? It will be generally great if with examples of use.
How can I see the package code, its functions? Where is it in C:/Go/? (maybe a stupid question, but it would be interesting to see what's there and how)
