# Welcome

Welcome to the **Yet Another Limelight Library (YALL)** documentation!

YALL is a WPILib vendordep that wraps [Limelight](https://limelightvision.io/)'s NetworkTables API and JSON results output in a typed, chainable Java (and Python) API for FRC robots. It replaces the raw `LimelightHelpers` script with real objects: a `Limelight` per camera, chainable settings, MegaTag1/MegaTag2 pose estimation, and typed results for every pipeline type, including AprilTag, retroreflective, neural classifier/detector, and barcode.

### Where to go next

* **Tutorials**: step-by-step walkthroughs for common setups.
* **How-to guides**: focused answers to specific "how do I…" questions.
* [**Tuning**](/documentation/tuning/tuning-workflow-overview.md): the tuning steps from Limelight's own documentation, reorganized into the order you'd actually apply them (sensor settings, crosshair/camera calibration, pipeline-specific tuning, then PID).
* **Understanding**: explanations of how YALL's settings, pose estimation, and results model work.
* **API Reference** (YALL-Gitbook-API space): every class, field, and method.
* [**Javadocs**](https://yet-another-software-suite.github.io/YALL/javadocs/): generated API docs.
* [**GitHub**](https://github.com/BroncBotz3481/YALL): source, issues, and releases.

# 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://yall.yassrobotics.com/documentation/welcome.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.
