# Install Truebit on Ethereum

{% hint style="info" %}
The Getting Started Guide has been updated to provide instructions on testing Truebit v1 using Hardhat and a locally forked Ethereum node. This replaces the previous version of the guide, which referenced the [deprecated Goerli testnet](https://github.com/eth-clients/goerli). The Goerli testnet is expected to sunset in early 2024, and Truebit recommends updating your test environment as soon as possible.

## Install Prerequisites

**1. Download & Install** [**Git**](https://git-scm.com/downloads)

```sh
git clone https://github.com/TruebitProtocol/truebit-eth
```

**3. Download & Install** [**Docker**](https://docs.docker.com/get-docker/)**.**

**4. Build the Truebit on Ethereum Docker container.**

```sh
docker pull truebitprotocol/truebit-eth:latest
```

**5. Install hardhat**

Create a new directory called "v1" and move into it

```bash
npm install hardhat@"2.20.1"
```

```bash
npx hardhat init
```

Copy the following file into the directory

{% file src="/files/ZLNgJYJ0YKaFkoHJvS0J" %}

Open the file and update the field \<YOUR\_INFURA\_API\_KEY> with your API KEY generated at the [Prerequisites](/v1docs/getting-started/master.md#register-on-infura-and-get-the-infura-api-key). Copy the following file into the directory.

Verify the Installed version to validate that the installed version corresponds to the "2.20.1"

```
npx hardhat --version 
```

**6. Register on Infura and get the Infura API Key.**

To fork from Ethereum Mainnet, you need a free Infura account.&#x20;
