# Quick Setup

### Hardhat – a tool for contract compilation and deployment

`Hardhat` is a development environment for Ethereum-compatible blockchains. It can automate, streamline and simplify repetitive tasks when building smart contracts and Dapps. It also provides developers with a built-in Hardhat network, a local Ethereum network specifically for deploying, testing, and debugging smart contracts

### Prepare the environment

#### Install Node.js

Hardhat is written in JavaScript. So we should make sure that Node.js (>=12.0) is installed.

* Ubuntu

```shell
sudo apt update
sudo apt install curl git
curl -sL https://deb.nodesource.com/setup_12.x | sudo -E bash -
sudo apt install nodejs
```

* MacOS

```shell
curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.35.2/install.sh | bash
nvm install 12
nvm use 12
nvm alias default 12
npm install npm --global 
```

#### Install Hardhat

We can start installing Hardhat after the Node environment is ready.

```
npm install --save-dev hardhat
```

## 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://relationlabs.gitbook.io/semantic-sbt/untitled/quick-setup.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.
