/*What is sharding?
In the discord context sharding basically means, splitting one
instance up to at most 1000 guilds (discord servers). Normally you
won’t need some special things to do when starting with your bot. 
But as I always say, forewarned is forearmed.
And if we are honest, we want our bot to be successful.*/
