# Install Docker

### 0. Make sure Docker is installed

[Official installation document](https://docs.docker.com/engine/install/)

* You can install it using the convenience script provided by Docker Use it at your discretion as it is [not recommended for production environments](https://docs.docker.com/engine/install/ubuntu/#install-using-the-convenience-script).

```
curl -fsSL get.docker.com | sudo bash
```

• If you are running docker commands using a non-root user, make sure it is in the docker group. To add the current user to docker group, run the following commands:

```
# Create the `docker` group
sudo groupadd docker

# Add your current user to the docker group.
sudo usermod -aG docker $USER

# Run the following command to activate the changes to groups
newgrp docker

# Verify that you can run docker commands without sudo
docker run hello-world
```

### **1. Download the Kusama snapshot**

{% hint style="warning" %}
This step currently is not easily executable. You can also skip it and progress to step 2.
{% endhint %}

1. Install **lz4** to be able to uncompress the snapshot

```
sudo apt update
sudo apt install snapd -y
sudo snap install lz4
```

2. Create **\~/mangatax** directory and download and unpack snapshot in one step into it:

```
# Create `~/mangatax/kusama/chains/ksmcc3` directory
mkdir -p ~/mangatax/kusama/chains/ksmcc3
# Download and unpack snapshot
curl -o - -L https://ksm-rocksdb.polkashots.io/snapshot | lz4 -c -d - | tar -x -C ~/mangatax/kusama/chains/ksmcc3
```

3. The chain data should now be in **\~/mangatax/chains/ksmcc3/db**

### 2. Download chainspec

```
curl https://raw.githubusercontent.com/mangata-finance/chainspec/master/mangata-kusama-mainnet.json > ~/mangatax/mangata-kusama-mainnet.json
```

### 3. Run the Collator

1. Add `docker-compose.yml` file to your home directory with the content below:

{% hint style="info" %}

{% endhint %}

```
