Download

Get the launcher at launcher.stygion.eu — the page detects your system and offers the right build (Windows, macOS, Linux). Download, install, run.

After install the launcher handles updates itself — it checks for a new version on every start and offers it. See Settings & updates.

First launch — the walkthrough

A short onboarding sets you up on first run:

1. Appearance — pick a theme and interface density. Nothing is locked; change it anytime in settings.
2. Data folder — where instances, downloaded Java and game files live. Default is the system data folder, but you can choose your own (e.g. another drive). Move it later and the launcher copies, verifies and switches safely — you lose nothing.
3. Account — sign in with Microsoft to play online, or continue offline. See Accounts.
4. Init — the launcher prepares what it needs and you're done.

Dashboard

After onboarding you land on the dashboard. From here:

• launch a modpack in one click,
• see recently played and the last 5 instances with a Play button,
• read the news.

The launcher runs in its own frameless window (search, account chip, window controls) with a sidebar — everything at hand.
