List your shop
You give the address and the amount. Everything else, the name, the description and the picture, is read from Telegram so the board says what the shop says about itself. Your listing goes in at whatever rank your bid buys: the top shop is on $150, so $151 takes first place outright.
Read this before you fill it in
You do not write the listing, Telegram does. The name, description and picture come from the account's own name, bio and avatar, so nobody can dress a listing up as something it is not. Change them at the source and they are what the board reads next time.
Nothing here can be edited afterwards. The only thing you choose is the @handle and the amount, so check the @handle carefully: get it wrong and every visitor is sent to the wrong place, and the only fix is paying for a second listing.
