# Initialization

### Install the SDK

Install the Context SDK to your TypeScript project using npm:

```bash
npm install @contextprotocol/sdk
```

### Setting Up Your Connection

To use Context, you always need a domain. This domain acts as your namespace within Context, where all your documents will be stored. Then, you'll need to obtain an API key for your domain.

You can claim your domain and generate the API key by creating an account at [app.ctx.xyz](https://app.ctx.xyz/).

Initialize the SDK:

```typescript
import { Context } from '@contextprotocol/sdk';

const ctx = new Context({ apiKey: "your_api_key_here" }); // Replace with your API key
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.ctx.xyz/developers/typescript-sdk/initialization.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
