# Before You Begin

## Step 1: Install binaries

To get started as quickly as possible we recommend using pre-built binaries. Building from source is a more advanced option but will set you back an hour or more and you may encounter build errors.

You can find how to build InfraBlockchain-Antelope from source [here](https://github.com/InfraBlockchain/infrablockchain).

The below commands will download binaries for respective operating systems.

### Mac OS X Brew Install:

{% hint style="info" %}
brew Install is not working now
{% endhint %}

```
brew tap infrablockchain/infrablockchain
brew install infrablockchain
```

If you don't have Brew installed, follow the installation instructions on the [official Brew website](https://brew.sh/).

### Ubuntu 18.04 Debian Package Install:

```
wget https://github.com/InfraBlockchain/infrablockchain/releases/download/v2.3.0-rc1/infrablockchain-2.3.0-rc1-amd64.deb
sudo apt install ./infrablockchain-2.3.0-rc1-amd64.deb
```

### Ubuntu 16.04 Debian Package Install:

```
wget https://github.com/InfraBlockchain/infrablockchain/releases/download/v2.3.0-rc1/infrablockchain-2.3.0-rc1-amd64.deb
sudo apt install ./infrablockchain-2.3.0-rc1-amd64.deb
```

### CentOS RPM Package Install:

```
wget https://github.com/InfraBlockchain/infrablockchain/releases/download/v2.3.0-rc1/infrablockchain-2.3.0-rc1.x86_64.rpm
sudo yum install ./infrablockchain-2.3.0-rc1.x86_64.rpm
```

If you have previous versions of Infrablockchain installed on your system, please uninstall before proceeding.

## Step 2: Setup a development directory, stick to it.

You're going to need to pick a directory to work from, it's suggested to create a `contracts` directory somewhere on your local drive.

```
mkdir contracts
cd contracts
```

# Agent Instructions

## 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.infrablockchain.net/infrablockchain-antelope/for-developers/developer-guides-infrablockchain-antelope-native/development-environment-infrablockchain-antelope-native/before-you-begin.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.
