# 1.2.4. Epic Subsystem

Epic Online Subsystem is an advanced framework based on Unreal Engine that provides developers with powerful tools to collaborate, modularize, and scale up their products easily. This system enables developers to connect various technologies easily and quickly, making their products more flexible and compatible with Epic products and other third-party services. Additionally, we leverage Epic Game Services to connect sessions, our internal networking system, and lobby services, which are submodules of Epic Online Services. The combination of these two powerful frameworks and our core system allows us to expand and improve our products, enabling us to react quickly to new integrations and collaborations.

## 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://litepaper.galaxiaverse.io/1.0.-introduction/1.2.-technology/1.2.4.-epic-subsystem.md?ask=<question>&goal=<endgoal>
```

`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.
