Open the BotFather Chat.
Type the /newbot to create a new bot. The BotFather will ask you for a name and username, then generate an authorization token for your new bot.
The name of your bot is displayed in contact details and elsewhere.
The Username is a short name, to be used in mentions. Usernames are 5-32 characters long and are case-insensitive, but may only include Latin characters, numbers, and underscores. Your bot’s username must end in ‘bot’, e.g. ‘pratglad_bot’.
