# Installation

> Install and run an Avail full node on Mainnet or Turing Testnet using pre-built binaries, Docker, or by building from source. This guide is minimal by design—no upgrade or misc. command sections.

## System requirements

| Component       | Minimum  | Recommended |
| --------------- | -------- | ----------- |
| RAM             | 8 GB     | 16 GB       |
| CPU (amd64/x86) | 4 cores  | 8 cores     |
| Storage (SSD)   | 20–40 GB | 200–300 GB  |

Prefer a stable Linux server distribution. Plan a persistent data directory (e.g., `/var/lib/avail`).

## Choose a network

* **Mainnet**: `--chain mainnet`
* **Turing Testnet**: `--chain turing` (if your binary supports it) or use the Turing **chainspec** from Network Info and pass its file path: `--chain /path/to/turing/chainspec.raw.json`.

## Option A — Pre-built binary (recommended)

1. Download the latest tarball from [**Releases**](https://github.com/availproject/avail/releases/) and extract it.
2. Run the node with a persistent data path:

```bash theme={null}
mkdir -p /var/lib/avail
./avail-node --name "<your-node-name>" --chain mainnet -d /var/lib/avail
```

**Run on Turing (testnet):**

```bash theme={null}
./avail-node --name "<your-node-name>" --chain turing -d /var/lib/avail
# or provide the explicit chainspec file if needed:
# ./avail-node --name "<your-node-name>" --chain /path/to/turing/chainspec.raw.json -d /var/lib/avail
```

## Option B — Docker

```bash theme={null}
docker run --restart=on-failure -d   -v /root/avail/node-data:/da/node-data   -p 9944:9944 -p 30333:30333   docker.io/availj/avail:<LATEST-AVAIL-NODE-VERSION>   --chain mainnet -d ./output --name "<your-node-name>"
```

**Turing (testnet):**

```bash theme={null}
docker run --restart=on-failure -d   -v /root/avail/node-data:/da/node-data   -p 9944:9944 -p 30333:30333   docker.io/availj/avail:<LATEST-AVAIL-NODE-VERSION>   --chain turing -d ./output --name "<your-node-name>"
```

Replace `<LATEST-AVAIL-NODE-VERSION>` with the latest tag from Docker Hub or the Releases page.

## Option C — Build from source

```bash theme={null}
# Install Rust (if missing)
curl https://sh.rustup.rs -sSf | sh
source $HOME/.cargo/env

# Build
git clone https://github.com/availproject/avail.git
cd avail
cargo build --release --locked

# Run (Mainnet)
mkdir -p /var/lib/avail
./target/release/avail-node --name "<your-node-name>" --chain mainnet -d /var/lib/avail
```

**Run on Turing:**

```bash theme={null}
./target/release/avail-node --name "<your-node-name>" --chain turing -d /var/lib/avail
# or with an explicit chainspec file:
# ./target/release/avail-node --name "<your-node-name>" --chain /path/to/turing/chainspec.raw.json -d /var/lib/avail
```

## Verify the node

* Logs should show peers and heights, e.g. `Idle (N peers), best: #<height> ... finalized #<height> ...`
* Check **Telemetry**: find your node by its `--name` under the **Mainnet** or **Turing** tab.
