# How to use in MultiMC
- Make a new instance in MultiMC with the wanted version of Minecraft.
- Click `Edit Instance` - it should open the `Version` page of the instance.
- Select the `Minecraft` component and click `Customize` - `Edit`. If you have not configured an external Text Editor in MultiMC Settings, this will attempt to open your system JSON editor.
- If the opened JSON has the `legacyLaunch` trait (for Minecraft versions 1.5.2 and older), then add the `noapplet` trait after it as well.
- For Minecraft versions 1.5.2 and older, set up an empty `assetIndex` instead of the vanilla pre-1.6:
```json
"assetIndex": {
"id": "empty",
"sha1": "62ea787c1f800c091b98678b050453a5ae59d7bc",
"size": 14,
"totalSize": 0,
"url": "https://mcphackers.github.io/assets/empty.json"
}
```
- If the opened JSON does not have a `libraries` array object (right after the `formatVersion` object), then add one. Add LaunchWrapper and its dependencies to the libraries to get an array like this:
```json
"libraries": [
{
"downloads": {
"artifact": {
"sha1": "120f6fdeb2602fa2d979ad0bdcd3c443a48148a6",

}
},
"name": "org.mcphackers.rdi:rdi:1.0"
}
]
```
- If the opened JSON does not have a `mainClass` string object (right before the `mainJar` object), then add one. Set or change the `mainClass` value to `org.mcphackers.launchwrapper.Launch`.
- If the opened JSON does not have a `minecraftArguments` string object (right after the `mainJar` object), then add one. Set or change the `minecraftArguments` value to something like `--username ${auth_player_name} --session ${auth_session} --gameDir ${game_directory} --assetsDir ${game_assets}` (you can see examples below or in [BetterJSONs](https://mcphackers.github.io/BetterJSONs/)).
# JSON patches for MultiMC instances
This allows changing the Minecraft version in the instance without re-editing the component, and easier interoperability with other MultiMC features. More information about JSON patches can be found [on the MultiMC wiki page about them](https://github.com/MultiMC/Launcher/wiki/JSON-Patches). Here is a [MultiMC instance](https://github.com/MCPHackers/LaunchWrapper/files/11588554/LaunchWrapperMCP-MultiMC.zip) demonstrating this.
## Examples
*Base your JSON on [BetterJSONs](https://mcphackers.github.io/BetterJSONs/)*
Instructions:
- Create a new MultiMC instance.
- Click "Edit Instance".
- Click "Add Empty". Enter "LaunchWrapper" for the name, and "org.mcphackers.launchwrapper" for the UUID.
- Select the new component labeled "LaunchWrapper", and click "Edit".
- Replace the contents of the file with something like this:

The existing version-specific information about creating a MultiMC instance should apply here (`minecraftArguments` should be customised as needed, `assetIndex` and `noapplet` can be removed for Minecraft 1.6 and onwards etc). The main difference between this and the existing instructions is that the format of the `libraries` array is different for JSON patches (`url` is treated like a maven repo).
```
- Save and close the document.
This should produce an instance similar to the attached one. I also edited mmc-pack.json to set `dependencyOnly` to be true on the LaunchWrapper patch, which prevents disabling it (optional).
