# License key

Each NFT grants one license key. One key can only be run on 1 device at a time. Once the bot has been closed on one device, you'll be able to run the bot with the same key on another device.

If you can't start the bot with your key, you should reset the binding of it from your current device. This can be done by sending `!reset YOUR_KEY_HERE`command to the Discord bot.
