# Signalbox documentation

> Signalbox routes the leads that come through your HubSpot forms. A flow you draw decides who each lead goes to and what the visitor sees next.

## Start here

### Quick start

Connect HubSpot, add the tag, publish a flow and give it to a form.

[Read the quick start](/get-started/quick-start/)

### Install guide

Ten pages that take a new workspace from nothing to a tested, live form.

[Open the install guide](/install-guide/what-signalbox-does/)

### Flows

How a flow runs, the fields it can read and the rules its conditions follow.

[Learn how a flow works](/flows/how-a-flow-works/)

### Agents

Connect Claude or another AI agent, and let it build and explain flows for you.
