+
+You will need to give it a modpack project ID. The project ID for [Extreme Optimization!](https://modrinth.com/modpack/extreme-optimization!) is `1oIpaoJo` for example.
+This can be found on the modpack page in the `Technical information` section in the left sidebar.
+
+You can also optionally specify a version ID. If you do not specify a version ID, the latest version will be used. The version ID for [Extreme Optimization!](https://modrinth.com/modpack/extreme-optimization!) version 1.12.2For2.0 is `SyMW2FDv` for example. This can be found on the modpack page by clicking the version number in the `Versions` section.
+
+The script will automatically setup of Forge, Fabric, or Quilt depending on the modpack.
+
+## Server Ports
