## Prerequisites (all languages)

Before installing any SDK:

1. [**Create a DNotifier account**](/product-docs/getting-started/register-account.md) and sign in at [app.dnotifier.com](https://app.dnotifier.com)
2. [**Create an app**](/product-docs/getting-started/create-app.md) and copy `appId` and `secret`
3. [**Store credentials securely**](/product-docs/getting-started/credentials.md) in environment variables
4. [**Choose your transport**](/product-docs/getting-started/choose-transport.md) — `ws` for realtime messaging, `http` for AI/RAG/workflows

## Recommended path

```
Install SDK  →  First connection  →  First message
     │                │                    │
     └────────────────┴────────────────────┘
              getting-started guides
```

1. **Install** — Add the package for your language (this section)
2. [**First connection**](/product-docs/getting-started/first-connection.md) — Construct `DNotifier`, call `connect()`
3. [**First message**](/product-docs/getting-started/first-message.md) — Send a 1:1 text message over WebSocket

## JavaScript / TypeScript

Install from npm:

```bash
npm install @dnotifier-realtime/dnotifier
```

Supports Node.js and browsers. Node requires a WebSocket implementation when using `transport: "ws"`.

## Dart / Flutter

Add to `pubspec.yaml`:

```yaml
dependencies:
  dnotifier: ^1.1.10
```

Run `dart pub get` or `flutter pub get`.

## Python

Install from PyPI:

```bash
pip install dnotifier
```

Requires Python 3.9+. The SDK is async-first (`async`/`await`).
