Grab the latest release for your platform from GitHub Releases.

Each platform uses its standard installer format. Run it and follow the prompts.

Windows: Enable Developer Mode

Polymerium uses symbolic links to share mod files across instances without duplication. On Windows, creating symlinks requires Developer Mode.

1. Open Settings → System → For developers
2. Toggle Developer Mode on
3. Confirm the prompt

This is a one-time setup. It doesn't compromise security — it only allows your user account to create symbolic links, which is the default on macOS and Linux.

macOS and Linux users don't need any special configuration — symlinks work out of the box.

First Launch: The OOBE Wizard

When you open Polymerium for the first time, the OOBE (Out-of-Box Experience) wizard walks you through:

1. Welcome & Features — a quick overview of what Polymerium can do.
2. Privilege Check — Polymerium tests whether it can create symlinks in its data directory. If this fails on Windows, you need to enable Developer Mode (see above).
3. Quick Setup — optionally configure Java paths and language.
4. Privacy — choose whether to send crash reports via Sentry.
5. Done — you're ready to create your first instance.

What Gets Installed Where

Polymerium stores all its data in ~/.trident/ on every platform. This includes settings, cached files, and your instances.
