The dashboard's Setup page walks you through each step and ticks it off when it sees it working, so you can stop and come back any time:

1. Connect Twitch and register the Twitch events, so support fills the meter and the bot can read chat.
2. Add the extension as an Overlay and open its Configuration once.
3. Choose where you play: request access to a server, or create a personal key for singleplayer.
4. Connect the game: servers connect by themselves; in singleplayer type /masucompanion and paste your key.
5. Link your Minecraft account with /companion link <code>, for every account you stream with.
6. Chat commands (optional): turn them on and make the bot a moderator.
7. Run your first vault.

When you step into the portal room, the squad reveal plays full screen in your game: the three viewers in this run's spotlight squad as 3D models in their own skins, tagged with how they got their seat. Your viewers watch it on your stream and their overlay tells each of them whether they made it.

It stays until you click or press Space (at most 30 seconds), so you can introduce the squad.

Then the Briefing opens. Pick the spice for this run with 1 2 3 or a click:

• Chill: each vote offers 2 blessings and a mild curse.
• Spicy: a blessing, a curse and a chaos effect.
• Chaos: stronger curses and chaos, and a bigger reward for the crowd.

The server can cap the highest spice. The spice locks when the vault timer starts.

While you are in the portal room, your viewers' overlay shows a full-screen predictions lobby: three questions about this run, staked with Masurium. The lobby closes and stakes lock the moment your vault timer starts, so take the time you need in the portal room.

Settlement pays out exactly what was staked. A result the game could not see is refunded, never guessed. Switch off any question under Predictions in the dashboard.

• Fate votes open every 3.5 minutes while the timer runs (the first after 1 minute) and stay open 45 seconds. The winner is applied to your vault and shown on your HUD. Effects tagged ×1–2 or ×1–3 roll how many copies land; Instant ones are crowd moments (Freeze Frame, Coin Rain, Launch, Shrink Ray) that happen at once and never use your mana. When an effect ends, your HUD and the overlay show what it did.
• The crowd meter fills from watching, votes, gems, Bits, subs, gift subs, hype trains and channel point rewards you map. When it fills, chat votes 20 seconds on an ultimate, including crowd casts such as Champion Call, Crowd Nova, Frost Nova and Totem Drop (the pack's own level 8 abilities, without your mana or cooldowns).
• Loot bursts fly across your viewers' video on a rare chest, a champion kill, an ultimate or the objective's reward crate.
• The spotlight squad follows you as small big-headed allies. They never fight, mobs ignore them and your attacks pass through them. Look at one to see its name and title; an ally that emotes walks into your view first.

Your HUD keeps everything on the edges of the screen; move any part in VH's HUD editor. When the vault ends, predictions settle and everyone who took part gets run XP and Masurium. If your game crashes, the run ends as aborted after 2 minutes and every stake is refunded.

Press End for the Control Deck: connection status, your linked account and access, the current run, previews of the Briefing and HUD that only you see, and the run tools. When something is wrong it says what and who fixes it.

Change the keys in Minecraft's Controls under MasuCompanion.

When a prediction's answer is known but nobody picked it, its stakes go into your channel's jackpot. Loot bursts add half the value of the gems no viewer grabbed (a burst nobody grabbed from adds nothing). Every question a viewer staked on since the last roll gives them one chance, whatever they staked.

At the end of your stream, open the Control Deck between runs and press Roll now twice: the roll plays full screen in your game and one viewer wins the whole pot. Or Keep for next stream to carry it over. MasuCompanion keeps no Masurium: everything in the pot goes back to viewers.
