[llvm-dev] How to submit a change for code review using arc

[Wink Saville via llvm-dev]

I've gone through Code Reviews with Phabriactor[1], Arcanist Quick
Start[2] and Arcanist User Guide arc diff[3]. But I'm unable to setup
reviewers my editor pops up and there is a "Reviewers:" line and but
I'm unable email addresses directly. It seems it wants reviewers
passed on the command line or some how in .arcconfig.

But I haven't been able to find any documentation on how to setup
reviewers so I've guessed you can add it to .git/arc/config:

What I've got now is my .git/arc/config is:
 {
  "editor": "vim",
  "reviewers": {
    "peterc": "peter at pcc.me.uk",
    "evgeniys": "eugeni.stepanov at gmail.com",
    "llvm-commits": "llvm-commits at lists.llvm.org"
   }
 }

My commit message is:
 $ git log -1
