Even though everything is well outlined in the video, I'll add the tools used, and cite the copyrighted stuff.

Also here's an img\text tutorial, in case that's more convenient.

1: join flagtrail Discord server, here.
2: register your account via the following command (just type it in #general chat in the server)
?register your-steem-user-name voting-weight-limit minimum-mana max-sp-for-engagement

So a proper command will look like something like this

?register imacryptorick 35 65 5000

Which means, my account will use up to 35% voting weight in flags (about 1.90$ at current prices).

No votes will be cast if my voting mana is below 65%.

And I will not flag anyone who has 50,000 SP or more.

Next you need to grant @flagtrail posting authority via the following steemconnect link
https://app.steemconnect.com/authorize/@flagtrail
Simple, yes?
