-# Run a Validator Node
+# Introduction
 
-The Aptos blockchain consists of validator nodes that run a distributed consensus protocol. The consensus protocol agrees upon the ordering of transactions and their results and then store both the transactions and output on the blockchain.
+This tutorial describes how to run Aptos nodes for the Aptos Incentivized Testnet 1 (AIT1) program. It explains the following:
 
-For incentivized testnet, we're recommending every node operator to run a validator with a fullnode, so all the reference implementation used here will have both nodes installed by default.
+- How to configure a validator node to run in test mode. This will be used during the AIT1 registration stage to validate your eligibility, and 
+- How to connect to the incentivized testnet if you are selected to run a validator node.

+
+For the AIT1, we  recommend that every node operator run both a validator node and a FullNode. Hence, the reference implementation described in these sections will install both the nodes by default.

+## Deploying for Aptos Incentivized Testnet
+
+In order to participate in the incentivized testnet, participants must demonstrate the ability to configure and deploy a node, as well as pass the sanctions screening requirements.
+
+Follow the below steps to participate in the Aptos Incentivized Testnet:
+- Follow the instructions to deploy both a validator node and a fullnode in the test mode.
+- Navigate to the [Incentivized Testnet registration page](https://community.aptoslabs.com/) and enter information about your node (pub-keys, IP/DNS address).
+- If you are selected to run a node, follow instructions in [Connecting to Aptos Incentivized Testnet](connect-to-testnet) to join incentivized testnet.
+- Keep the node in healthy state for the entire testing period and follow operational requests as needed.

 ## Getting started
-You can configure an Aptos node in many ways: using Aptos source code, Docker, and Terraform. For best availability and stability, we recommend you to deploy your node on the Cloud. We have provided Terraform support for deploying the node on three cloud providers: GCP, AWS and Azure.

+### Installation
+You must run a validator node in test mode to be eligible for incentivized testnet. This is a method we use to verify that a node operator can successfully start a validator node, and have it properly configured with Aptos network identity. 
 
-High level steps for joining Aptos Incentivized Testnet:
-- Follow the instruction to deploy a node (including a validator node and a fullnode) with test mode.
-- Navigate to registration page, enter informations about your node (pub-keys, IP/DNS address).
-- If you're selected to run a node, follow instructions to join incentivized testnet.
-- Keep the node in healthy state for the entire testing period and follow operational requests as needed.
