# Nodes reference

> One page per node type: ports, parameters, how it works and playable help patches.

Every node in the catalog has a page generated from `packages/node-docs` and the node catalog, so the ports and parameter tables always match the app. Each page has the node's ports, parameters with ranges and defaults, an explanation, and ordered **help patches**: small Toys that each teach one idea, shown as a static diagram and Frame preview with an **Open in TuneToys** link.

Nodes are grouped by category below.
