FWIW: I (@rondy) am not the creator of the content shared here, which is an excerpt from Edmond Lau's book. I simply copied and pasted it from another location and saved it as a personal note, before it gained popularity on news.ycombinator.com. Unfortunately, I cannot recall the exact origin of the original source, nor was I able to find the author's name, so I am can't provide the appropriate credits.

→ Great great documentation about all this (so much better): https://github.com/drduh/YubiKey-Guide

Using Yubikey (PIV on osx, etc.)

Documentation for PIV: https://github.com/Yubico/yubikey-piv-manager/tree/master/doc

Using GPG key

brew install gnupg, pinentry-mac (this includes gpg-agent and pinentry)
Generate a key: $ gpg --gen-key
Take the defaults. Whatevs
Tell gpg-agent to use pinentry-mac:
```
$ vim ~/.gnupg/gpg-agent.conf 
```

Bot initializers now only use named parameters. This shouldn't be a hard change to adjust to, but everyone will have to do it. Here's some examples:

# Previously
bot = Discordrb::Bot.new 'email@example.com', 'hunter2', true

# Now
bot = Discordrb::Bot.new email: 'email@example.com', password: 'hunter2', log_mode: :debug

# Previously
