+# EC2 Instance Requirements
+
+The following requirements describe the optimal EC2 Instance for running a Casper node.
+
+| Requirements | Description          |
+| ------------ | ---------------------|
+| O.S.         | Ubuntu 20.04 LTS     |
+| RAM          | 32 GB                |
+| Disk Space   | 2 TB                 |

+## EC2 Instance Ports
+
+The following ports are open to run the Casper service successfully:

+
+## EC2 Instance Configuration
+
+The `casper-node-install-configure.sh.tftpl` is a template that converts to a bash file when Terragrunt runs. It contains all the installation and configuration commands the `casper-service` and monitoring services (e.g., CloudWatch Agent and Grafana) need. This bash file calls other bash files to finish the configuration for backup and CloudWatch.
+
+To see more configuration files, go to the config module. You will see a detailed explanation of the other configuration files referenced inside the code of the `casper-node-install-configure.sh.tftpl` file. This file needs to be separated because there is a character limit for script templates in AWS.

+## EC2 Instance Creation
