Reaction roles are a simple method for letting your server members add and remove roles from themselves without needing an administrator or someone with power to give them such role.

Setting up reaction roles are fairly simple; the main commands are reactionroles add and reactionroles remove, please note that reactionroles remove will clear all reaction roles on a message. The method for setting up a reaction role goes the following way

/reactionroles add [Message ID] [@role] [Emoji]

We can get the message id via right-clicking a message in developer mode, next we need to ping the role (@role) and finally we add an emoji at the end. All together it should look something like this

/reactionroles add 812328696878596166 @Nekos 😆

Removing a reaction role is as simple as using the removeReactionRole command; an additional reminder that this will wipe all reaction roles from a message

/reactionroles remove <Message ID>
