This is pretty easy here is a step-by-step guide:

1. Invite the bot when you don't already have it. You can do this by clicking here "Invite".

2. Go on kick.com and get the link to the streamer you want to create a leaderboard for. The link should look like this "https://kick.com/xqc". You can also just copy the name for example "xqc".

3. Use the /subscriber role command inside your Discord Server, and paste the link or name you copied into the "streamer" option. Then, specify the desired channel where the bot should send the message to And select your role that should be given to subscribers.

3.1 If you want you can also set a custom message in the "message" option. This don't allow custom variables!

5. Done! The message should be already sent.

Note: Make sure the bot have the required perms to send the message in the channel and to give / manage roles.

This is straightforward. If the user subscribes to the streamer, the person only needs to click on the button below of the message the /subscriber role command sends.
