# Cesium

A Minecraft PvP client that loads into a game you already have open.

Cesium is a set of PvP modules, a ClickGUI to control them, and configs to save how you have them set. It does not install into Minecraft. You open Minecraft the way you always do, then the Cesium Launcher loads the client into that running game.

{% hint style="info" %}
Cesium is in beta. Access is free and is handed out in the Discord server at [cesiumclient.com/discord](https://discord.gg/3QBFFwbbH). Cesium and Cesium+ are not on sale yet.
{% endhint %}

## How it works

  A[You open Minecraft] --> B[Cesium Launcher]
  B -->|Load Cesium| C[Client loads into the running game]
  C --> D[ClickGUI, modules, configs]
```

There is nothing to install into Minecraft and no restart. Start the game, press one button in the launcher, and Cesium is in. Every build is signed, so what the launcher loads is what Cesium shipped.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://cesium.gitbook.io/cesium-docs/cesium.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
