Trying to expand concat Wiki, cannot formally pull request, maintainer review/merge would be appreciated

[DeerTears]

Hi! I've really appreciated this tool and I saw the Wiki page for client IDs which was super useful for me. I'd like to pay it forward and expand the wiki a bit just to cover this program in more detail, and to add/update links to the new wiki pages in the readme and this program's error messages.

I cannot push my wiki to this repo because github doesn't do pull requests on wikis. You could essentially rebase this repo's wiki with the wiki in my fork. You can get my wiki files by cloning my fork's wiki, copying those files, and applying it to your own wiki. The main.go file would also need any wiki links updated to the new page titles/headers as needed.

My fork isn't perfect yet but I at least wanted to start this dialog. Let me know what you think: https://github.com/DeerTears/concat/wiki

I think I prefer having most of the information in the readme of the repo instead of in the wiki. I think only few people actually check the wiki of a project.
