 ## Objective
+
 The document will contain essential instructions and knowledge for a node operator to successfully run a Tangerine BP node.
 
 ## Background
+
 For node operator to easily establish a Tangerine BP node and continuously run the node for mining rewards, Tangerine foundation provides the well-designed software supporting the mining mechanism on Tangerine blockchain.
 
 ## Overview
+
 The guide has 3 sections, providing the required knowledge for a node operator to: Set up node, run software, and collect mining rewards.
 
 ## Environment Setup
+
 How to set up AWS/GCP server?
