# Node-RED Manual Index

This folder summarizes official Node-RED docs that are relevant to EVOLV node development.

## What To Check First (EVOLV)

1. Runtime routing in `src/nodeClass.js`: use explicit output arrays for multi-output nodes.
2. Input handlers: use `send` + `done` pattern from Node-RED runtime docs.
3. Function nodes in example flows: return arrays with output-position alignment.
4. Editor/runtime parity: properties in `RED.nodes.registerType(...defaults...)` must map to runtime config parsing.
5. For FlowFuse dashboard reference, see:
