Go to metamask and set up a wallet, but I would advise against this unless you have taken proper security precautions like keeping your crypto on a pc that doesn't have an internet connection. Some brokers offer crypto like wealthsimple but their selections are limited and you technically don't have custody of any of your coins, which is perfectly fine to get started out. When/if these precautions are met you can transfer your coins to your wallet from said broker but afaik this system is in beta for now
