You have a minor misspelling in the following sentence:

that's the first contract that you'll need to use if you want a smart contract to be able to find you in the sidechain (I would say that it's the only requirement to use the sidechain, the sidechain is totally independant from the Steem blockchain and doesn't know anything about it so for example if you want to issue tokens to an account then you need to make sure that this account exists on the Steem blockchain, so that's the workaround to help with that).
