-# Discord input for micro-bot
-[Discord](https://discordapp.com) support for micro bot based on [discordgo](github.com/bwmarrin/discordgo).
-
-This was originally written by Aleksandr Tihomirov (@zet4) and can be found at https://github.com/zet4/micro-misc/.
-
-## Options
-### discord_token
-
-You have to supply an application token via `--discord_token`.
-
-Head over to Discord's [developer introduction](https://discordapp.com/developers/docs/intro)
-to learn how to create applications and how the API works.
-
-### discord_prefix
-
-Set a command prefix with `--discord_prefix`. The default prefix is `Micro `.
-You can mention the bot or use the prefix to run a command.
-
-### discord_whitelist
-
-Pass a list of comma-separated user IDs with `--discord_whitelist`. Only allow
-these users to use the bot.
