As mentioned on the main page, Miyu always listens to text commands with its own default prefix m! or its mention @Miyu, followed by the command you want to use.
Additionally, you can set a custom prefix for your server to avoid having an overlap in command usage with others bot you might have added on your server.
Here is a quick overview of all prefix commands:
To show all available prefix for your server, use the m!prefix command. If a custom prefix is configured it will show that one as well, next to the two default prefixes.
To set a custom prefix for your server you can also use the m!prefix command followed by the new prefix you want to set: m!prefix !.
A custom prefix cannot be longer than 4 characters.
A custom prefix cannot contain
*,`or~.
You can remove your set custom prefix by using the m!remove prefix command.
