+## Installation
+
+Our modpack is intended to be played with [MultiMC](https://multimc.org). Other launchers may work, but you'll be on your own figuring out how to set that up. I'm not entirely sure when the modpack will be stored, so I won't mention how to obtain it for now. Just know that you'll have a zip downloaded that you got somewhere.
+
+1. Once you have MultiMC installed, you will need to add your Minecraft account. This is _specifically_ for the Java edition of Minecraft. You most likely have a Microsoft login, or maybe a Mojang one. In the image, my account is shown, but if you just installed this it will probably be blank. Click the circled area and select "Manage Accounts". If that doesn't work, you can also get there by clicking `Settings` then `Accounts`.

+
+2. With your account set up, you're ready to create an instance. Click the `Add Instance` button, then select `Import from zip`. Use the browse button to find the zip you downloaded and select it.
+
+3. That's it. The zip _should_ include the auto-updater, so you won't have to do this again when we update the pack.
+
+### Optional Mods
+
+We've got a few QoL mods that you might want. None are critical to the experience, so we made them optional. When you launch the pack, you can click the circled button to configure which ones you want. Once you do, they will remain automatically checked for future updates.
