+# Node-RED Manual Index
+
+This folder summarizes official Node-RED docs that are relevant to EVOLV node development.
+
+## Official Sources
+
+- Creating Nodes: JavaScript file and message handling  
+  https://nodered.org/docs/creating-nodes/node-js
+- Creating Nodes: Edit dialog and node definition in `.html`  
+  https://nodered.org/docs/creating-nodes/edit-dialog
+- Working with messages  
+  https://nodered.org/docs/user-guide/messages
+- Writing Functions (return arrays, multiple outputs, async send/done)  
+  https://nodered.org/docs/user-guide/writing-functions
+
+## 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:
+   - `flowfuse-widgets-catalog.md` — master index of all 22 widget types
+   - `flowfuse-ui-chart-manual.md` — chart widget (line, bar, scatter, pie, histogram)
+   - `flowfuse-ui-gauge-manual.md` — gauge widget (tile, battery, tank, half, 3/4 arc)
+   - `flowfuse-ui-text-manual.md` — text display widget
+   - `flowfuse-ui-template-manual.md` — custom Vue/Vuetify template widget
+   - `flowfuse-ui-button-manual.md` — button widget
+   - `flowfuse-ui-config-manual.md` — config nodes (ui-base, ui-page, ui-group, ui-theme)
+   - `flowfuse-dashboard-layout-manual.md` — layout patterns and sizing rules
