The first thing you need to do is register for access to OST Platform. With access to the OST Platform, you will use the Token Setup page to set a Token Name, Token Identifier and a conversion rate between your Brand Token and OST. Optionally you can install MetaMask to associate an Account Owner Address with your account and manage an initial allotment of OST-Test for the Sandbox environment, then go ahead and set up a Brand Token. Once set up, you can mint Brand Tokens by simply setting the required number of tokens to mint and confirming the mint request. A detailed walk through of the steps to create a Brand Token can be found here.
