# Installation

> Install the Elding SDK.

```bash theme={null}
npm install @elding/sdk
```

<Warning>
  Always use the **scoped** name `@elding/sdk`. `npm install elding` (without the
  `@elding/` scope) installs an **unrelated** third-party package, not Elding.
</Warning>

## Recommended: `configure()`

Write your HTTP API integrations once and use them in both development and production.
Switching between the local proxy and direct provider access is automatic.

  The recommended pattern: write once and deploy anywhere.

<Note>
  Elding only handles HTTP API keys. `DATABASE_URL`, `JWT_SECRET`, `REDIS_URL`, and other
  non-HTTP variables remain with your hosting platform.
