# Introduction

> Ground indexes your code and docs and serves fast hybrid and RMH search with citations and agent APIs.

# What is Ground?

Ground is a **retrieval and indexing platform** for coding agents: it ingests repos, documentation, OpenAPI specs, PDFs, and public packages, then serves **hybrid search** (vectors + keywords), **RMH search** (multi-round / neighbor expansion), **streaming chat** with citations, **Rover** (GitHub exploration jobs), and **on-demand package search**.

* **Provenance**: Results carry citations (source, path, lines, version where applicable).
* **Freshness**: Sources have sync metadata; policy controls how stale content is treated.
* **Quality signals**: Evidence counts, staleness summaries, and optional conflict surfacing for divergent definitions.

## Why Ground?

1. **Index your sources** (Git, HTML docs, OpenAPI, npm/PyPI, PDFs).
2. **Query with hybrid + RMH** when you need more than a single top-k list.
3. **Wire agents** through the REST API or **MCP** using your API key.
