# Nulink Horus 2.0 Testnet (Phase 1) By [jab0ykn0ws](https://paragraph.com/@jab0ykn0ws) · 2024-01-14 --- As the decentralized landscape continues to evolve, NuLink emerges as a key player in the realm of privacy-focused solutions for decentralized applications. If you're eager to explore and contribute to NuLink's ecosystem, setting up a Horus testnet node is a great way to get started. In this step-by-step guide, we'll walk you through the process of setting up your NuLink Horus testnet node, allowing you to actively participate in the development and testing phases of this innovative project. First lets look at the testnet milestones broken down by Phase ([source](https://docs.nulink.org/products/testnet/horus_milestones)) ![Horus 2.0 Phases](https://storage.googleapis.com/papyrus_images/4a2abdca19e8f8cf21f40a9a2546113456206cee1e5f8f87f5824a2638baa80d.png) Horus 2.0 Phases We are currently at Phase 1 and we will do Number 2, which is the [Worker Node Installer Testing](https://docs.nulink.org/products/stakers/nulink_worker/worker_install). **Setup your NuLink Dashboard** ------------------------------- * Access the NuLink dashboard here [https://dashboard.testnet.nulink.org](https://dashboard.testnet.nulink.org) * Connect your wallet (we are using Metamask here on this guide) and switch to BSC Testnet. * Claim some test tokens from the faucet _(see screenshot below)_ ![Claim tokens from faucet](https://storage.googleapis.com/papyrus_images/e4d6b0e20804a8579bf384029e55a2eb4fbdda4b7ef8913123a14c583f3b74ef.jpg) Claim tokens from faucet * Head to staking tab and stake 5 tNLK tokens ![Stake 5 nTLK tokens](https://storage.googleapis.com/papyrus_images/dce9c3443e080f8f1a76778dc0d76a6d14820710990aa86778c4f896ed299083.png) Stake 5 nTLK tokens * Prompts will appear on your Metamask click on approve and sign. **Setup our Worker Node** ------------------------- * Launch your VPS on any provider, for this guide we will use [Contabo](https://contabo.com/). * Select Cloud VPS S ![](https://storage.googleapis.com/papyrus_images/5a6d9a1db04161ee66ea8f1f86dafad75412e9a7beb2fe6a8da91b90e8c3cc96.png) * Click on Apps & Panels and select Docker and choose Ubuntu 22.04 from the dropdown. ![](https://storage.googleapis.com/papyrus_images/9ef1decc628bce27eb77fbceb546cb81634a8806594b52a7f6587475bba0c2bf.png) * It will take a few minutes before your server is ready.
