Complete setup checklist for LiteLoader (Legacy 1.7.10 – 1.12.2) on Windows: version selection, None (can chain alongside Forge), and shader/mod installation.

- **Supported Versions:** 1.5.2 – 1.12.2
- **Required Library:** None (can chain alongside Forge)

## Step-by-step LiteLoader (Legacy 1.7.10 – 1.12.2) instance creation

1. Launch Prism Launcher (available at [/download](https://prismlauncher.ink/download)) and click **Add Instance** on the top toolbar.
2. Pick your target Minecraft version (1.5.2 – 1.12.2) and select [LiteLoader (Legacy 1.7.10 – 1.12.2)](https://prismlauncher.ink/loaders/liteloader-legacy) under the Mod Loader section, then click **OK**.
3. Right-click the new instance → **Edit** → **Mods** → **Download mods** and install `None (can chain alongside Forge)` along with your favorite mods.
