torrc: Comments Need Clarifying
I've written a guide on how to set up a Tor relay, but I ran into some confusion from readers on some initial drafts on a few areas which I clarified on the final guide (see: https://motherboard.vice.com/read/how-you-can-help-make-tor-faster-for-10-a-month). However, it'd be great to see some clarifications in the comments in /etc/tor/torrc.
Uncomment this if you run more than one Tor relay, and add the identity
key fingerprint of each Tor relay you control, even if they're on
different networks. Include the "$" with each key ID.
Don't forget the < and >.

A handle for your relay, so people don't have to refer to it by key.
Only alphanumeric characters, A-Z, a-z, 0-1 allowed. No unicode, no emoji.
I assume this might be easy, but that it might trigger some package management systems to bug the user into asking which config they want if they already have the tor package installed.
