# Installation (Holesky/Mainnet)

> Run the Aligned Layer Operator binary using the official steps. This guide is trimmed to the essential build, configure, and start sequence.

<Note>
  **Note:** You must be [**whitelisted**](https://docs.google.com/forms/d/e/1FAIpQLSdH9sgfTz4v33lAvwj6BvYJGAeIshQia3FXz36PFfF-WQAWEQ/viewform) to operate on Aligned. Current operator version in docs: `v0.19.1` ([check docs for updates](https://github.com/yetanotherco/aligned_layer/releases/tag/v0.19.1)).
</Note>

## 1) Requirements

* Linux x86\_64
* Go, Rust, Foundry
* Build deps: `pkg-config`, `libssl-dev`, `g++`

| **Component** | **Specification** |
| ------------- | ----------------- |
| **CPU**       | 16 cores          |
| **Memory**    | 32 GB RAM         |
| **Bandwidth** | 1 Gbps            |
| **Storage**   | 256 GB disk space |

## 2) Clone and build

```bash theme={null}
git clone https://github.com/yetanotherco/aligned_layer.git --branch v0.19.1
cd aligned_layer

# Install Foundry
make foundry_install && foundryup

# Build operator (testnet example: Holesky/Hoodi)
make operator_build ENVIRONMENT=testnet

# For mainnet build:
# make operator_build ENVIRONMENT=mainnet
```

## 3) Configure your operator

Provide RPC endpoints, keys, and strategy-specific settings in your config file(s). See the docs for the required fields and supported strategies list.

## 4) Register the operator

Follow the registration step in docs (requires whitelisting and EigenLayer operator registration).

## 5) Start the operator

```bash theme={null}
# From the repo root, using your config
./operator/build/aligned-operator --config <path_to_config.toml>
```

(Optional) Run with systemd as shown in the docs for persistence.

## 6) Check version & status

```bash theme={null}
./operator/build/aligned-operator --version

# Telemetry (replace <operator_address>):
# Mainnet
