# App with SDK

If you're building an app, the SDK is the best way to integrate Channel3.

## Option A — Coding agent + skill

```bash theme={null}
npx skills add channel3-ai/skills --skill channel3-api
```

Optional UI (React + shadcn):

```bash theme={null}
npx shadcn@latest add https://ui.trychannel3.com/r/all.json
```

Then prompt:

```text theme={null}
Build a shopping experience using the Channel3 skill, Channel3 SDK, and Channel3 UI components. Top: text and image search with filters. Results in a grid; click opens a PDP with variants, similar products, and a way back.
```
