remark-ping: docs mention zestedesavoir, not how to set it up?

I suggest the docs show how to configure remarkPingZds for your own site!

Ok so let’s recap:

.use('remark-ping', {
  pingUsername (username) {
    return doWhateverReturnTrueIfUsernameCanBePinged(username)
  },
  userURL (username) {
    return `https://github.com/${username}`
  },
  usernameRegex: /[\s'"(,:<]?@(?:\*\*([^*]+)\*\*|(\w+))/,
})
