# 6.1.1 Using ethers.js

To begin, ethers.js must be installed in your project environment.

Open your terminal and run:

```
npm install ethers
```

This command downloads and installs the ethers.js library into your project, making its functionality available in your code.

Once installed, a connection to the FreCx network can be created by initializing a provider. The provider is responsible for sending requests to the blockchain.

```
const { ethers } = require("ethers");
const provider = new ethers.JsonRpcProvider("https://rpc.frequencychain.org");
```

At this stage, the application is capable of reading data from the blockchain. However, to send transactions (such as updating contract state), a wallet must be connected.

```
const wallet = new ethers.Wallet("YOUR_PRIVATE_KEY", provider);
```

This wallet object is now capable of signing transactions and interacting with smart contracts on behalf of the user.

## 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.frequencychain.org/6.-interacting-with-smart-contracts-using-ethers.js-and-web3.js/6.1-establishing-a-connection-to-the-frecx-network/6.1.1-using-ethers.js.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.
