# Learn fxnode

Treat this as a trail map rather than a giant manual.

## Start

Build [your first node](/learn/tutorials/first-node), then tour [all examples](/learn/examples/).

## Build

Use the [browser-host guide](/learn/guides/browser-host) to connect your DOM and the [interaction guide](/learn/guides/interactions) to translate input.

## Understand

Read [worker authority](/learn/concepts/worker-authority), [composition](/learn/concepts/composition), and [state and persistence](/learn/concepts/state-and-persistence).

## Integrate

Check [browser support](/learn/guides/browser-support), [CSP](/learn/guides/csp), lifecycle, and [accessibility](/learn/guides/accessibility) before shipping.

## Reference

When you know the concept and need an exact signature, use the [API Reference](/reference/).
