Where can I find a fully elaborated explanation of the duties surrounding Sunday?

[Supercomputer]

I get the gist of it since I searched online for examination of concience.

Go to Mass on Sunday except when it is not possible or too costly.
Avoid work except when it is not possible or too costly.

However, I want to incorporate more detail into my understanding.

Be advised I simply would like a link to the proper official documentation along with specific chapter/section info to locate the pertaining passages. It is not nessasary to restate or quote the info since I will want to read the original anyway.

Thanks very much. Just reply if you know what I am looking for. I do not want to send anyone on a wild goose chase. I honestly do not know where to find it but I am asuming it exists.
