# Packwiz [Packwiz](https://github.com/comp500/packwiz) is a tool for making self-updating modpacks for MultiMC. The best way to update it for Fabulously Optimized is to just create a CF pack and update the Packwiz manifests (`index.toml` and the hash of `pack.toml`) via the terminal: ``` .\packwiz.exe curseforge import filepath ``` After that it is possible to just use the MultiMC pack created in MultiMC-Packwiz, instructions are in the Packwiz repo. Requirements: 1. [Download the manifest creating executable from here](https://github.com/comp500/packwiz/actions) and place it to `../Packwiz`. 2. [Download the MultiMC bootstrap from here](https://github.com/comp500/packwiz-installer-bootstrap/releases) and place it to `../MultiMC-Packwiz/Fabulously Optimized (auto-update)/.minecraft`
