## Connect to the Testnet (Using Binary)

Pando Lab maintains a testnet environment that resembles the mainnet to facilitate partner development and testing. 

To connect to the testnet, open a terminal, and follow the steps below.

### Step 1- Go Environment

First, we need [**`Setup Go environment`**](https://docs.pandoproject.org/pandoproject/blockchain-integration#setup-go-environment) a system, please refer to our respective documentation for the same. 

### Step 2 - Binary download

In 2nd step, we need to download and place the binary in the following directory

```shell
/usr/local/go/bin/
```

To download the Binary compressed file we need to enter the following command 

```shell
wget https://testnetblockchainupdates.s3.ap-southeast-1.amazonaws.com/pando.tar.gz
```

```shell
wget https://testnetblockchainupdates.s3.ap-southeast-1.amazonaws.com/pandocli.tar.gz
```

Unzip this and place in the directory mentioned above

```shell
tar <filename>.tar.gz -C /usr/local/go/bin/
```

### Step 3 - Snapshot and config

In this step, we need to download and place a **snapshot and config.yaml** in the following directory

```shell
/$homeDir/testnet/node/
```

1. To download the latest **snapshot** of testnet we need to enter the following command&#x20;

```shell
wget https://testnetblockchainupdates.s3.ap-southeast-1.amazonaws.com/snapshot
```

2\. To download the config file of testnet we need to enter the following command&#x20;

```shell
wget https://testnetblockchainupdates.s3.ap-southeast-1.amazonaws.com/config.yaml
```

### Step 4. Launch and connect to the testnet

Start a new session, and use the following commands to launch a node and connect to the pando network testnet. It may take some time to download the blockchain data to be in sync with the network.

Shell

```shell
pando start --config=../testnet/node
```

**Note:** when the testnet Pando Node is launched for the first time, you need to choose a password to generate an address for the node. Please choose a secure password and keep it in a safe place. The next time when you launch the node again, you will need the password to unlock it.
