# Start Developing
To interact with the Keeta Network, we’ve built the **KeetaNet SDK** — a JavaScript and TypeScript-compatible library that works in multiple environments, including **Node.js**, modern **web browsers**, and other JavaScript runtimes.
Whether you're building server-side applications or browser-based dApps, the SDK gives you everything you need to connect to the Keeta Network, manage accounts, send transactions, and more.
## Installation and Type Support
The SDK includes full TypeScript definitions, so you’ll get autocomplete and inline type checking in modern editors. You can install it from npm:
```bash
npm install @keetanetwork/keetanet-client
```
Type definitions are bundled with the package — no need to install anything extra.
## Using the SDK in NodeJS
In Node.js, you can import the KeetaNet SDK like this:
```typescript
import * as KeetaNet from '@keetanetwork/keetanet-client';
```
Once imported, the SDK exposes several modules and utilities. The most important starting point is the `UserClient`, which lets you connect to the network and perform operations like sending tokens or fetching blockchain data.
```typescript
const signer = KeetaNet.lib.Account.fromSeed(mySeed, 0);
const client = KeetaNet.UserClient.fromNetwork('test', signer);
```
## Using the SDK in the Browser
You can also use the KeetaNet SDK directly in a browser using a script tag. Here's a basic example to get started:
```html
```
This is a good way to get started quickly without any build tools. Just keep in mind: **don’t store or expose real private keys or seeds in client-side code** in production apps.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.
## 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.keeta.com/introduction/start-developing.md?ask=&goal=
```
`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.
