The manual way

Download Psi on Modrinth

Download the latest Psi file from Modrinth for your Minecraft version.
Install Forge and NeoForge and launch Minecraft once so the loader profile is created.
Drop the downloaded .jar into your mods folder (the mods folder inside .minecraft, or your server's mods folder).
Add any libraries Psi depends on (the Modrinth page lists them) into the same folder, then start Minecraft on the Forge and NeoForge profile.

Psiversions & compatibility

Psi targets Forge and NeoForge. Orca matches the right loader and Minecraft version for you when you host or play it, so you never have to line them up by hand. For the full list of supported Minecraft versions and required dependencies, check the Modrinth page.
