Download Cezium on Modrinth

Download the latest Cezium file from Modrinth for your Minecraft version.
Install Fabric 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 Cezium depends on (the Modrinth page lists them) into the same folder, then start Minecraft on the Fabric profile.
