# MultiMC
{% hint style="info" %}
Consider [using Prism Launcher](/install-instructions/prism-launcher.md) instead, as it has a similar interface but more features.
{% endhint %}
{% tabs %}
{% tab title="Default" %}
1. Download, install and launch [MultiMC](https://multimc.org) and Java
* [Java 25](https://download.fo/java25) for Minecraft 26.x or [Java 21](https://download.fo/java21) for Minecraft 1.21.x
2. Click `Add Instance`
3. Select `Modrinth` tab from the left
4. Select "Fabulously Optimized"
5. Click `OK`
* Optional: Select the version you want by selecting it on the dropdown before you click `OK`.
6. The modpack will now install.
7. Once installed, double-click the icon to play.
{% endtab %}
{% tab title="Auto-update" %}
1. Download, install and launch [MultiMC](https://multimc.org) and Java
* [Java 21](https://download.fo/java21) for Minecraft 1.21.x or [Java 25](https://download.fo/java25) for Minecraft 26.x
2. Download the pack for your preferred Minecraft version:
26.2 26.1.2 1.21.11 1.21.10 1.21.8 1.21.5 1.21.4 1.21.1 1.20.6 1.19.4 1.18.2 1.17.1 1.16.5
* Other versions can be found from [GitHub Releases](https://github.com/Fabulously-Optimized/fabulously-optimized/releases)
3. Drag the ZIP-archive to MultiMC window, and hit OK in the window that pops up.
4. Double-click that version you just created to download and launch the modpack
Got asked to download a mod manually?
If you get asked to download a specific jar, it means we are not allowed to bundle it and you must add it manually:
1. Copy and paste the given address to your browser
2. Click `Cancel Launch`
3. Click `Download` on the mod
4. On MultiMC, click on the instance, then click `View Mods`
5. Drag the downloaded mod into the mod list
6. Click `Launch`
How does this work?
It is a normal MultiMC modpack that simply launches [packwiz](https://github.com/comp500/packwiz), a mod handling tool on every start.
Every time you launch it, it asks the server whether the modpack has any updates. This means you do need internet access or you'll get an error (though you can skip the error). If there are any, they will be downloaded and launched, otherwise the current game will launch.
It does *not* auto-update any individual mods outside of what is set in the modpack.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://wiki.download.fo/install-instructions/multimc.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
