# Start from a native example

> Use only examples selected for the native Worker contract.

- Canonical page: https://docs.userland.fun/quickstarts/from-example/
- Docs index for agents: https://docs.userland.fun/llms.txt

> **For agents:** Read the [complete native guide](/native-guide.md) and current `context.get` capabilities. Use only implemented operations and preserve exact Account, app and environment authority.

Read the current [example catalog](/examples/catalog.json) and `context.get` before choosing a starting point. A listed example must use normal Worker source, native configuration and explicit secret requirements. Old custom-runtime examples are not a native implementation guide.

Keep the original files and migrations together. Apply a private preview with the intended Account, inspect the operation and exercise the example's essential flow. Change source with exact revision and file-hash preconditions; do not rebuild an existing app from an outdated example copy.

An example demonstrates its declared behavior. Add the authentication, abuse controls, external services and product-specific policies your app needs, and test them. No example proves a commercial entitlement or every client transport.
