+## Building an AMI based on Amazon Linux
+
+This guide provides step-by-step instructions for building your own Amazon Linux AMI image.
+Follow the instructions below to configure and build the image successfully.
+
+### Step-by-Step Instructions
+
+To build an AMI based on Amazon Linux you need to update the install_graphdb.sh script.
+This script installs necessary tools and configures the environment. Follow these steps to modify the script:
+
+1. Open the install_graphdb.sh script in a text editor.
+2. Replace the existing content between lines 12-36 with the following code:
+
+```bash
+# Install Tools
+yum update -y
+yum install -y java-11-amazon-corretto
+
+# Get the server architecture and corresponding AWS CLI
+server_arch=$(uname -m)
+
+if [[ "$server_arch" == "x86_64" ]]; then
+  curl "https://amazoncloudwatch-agent.s3.amazonaws.com/amazon_linux/amd64/latest/amazon-cloudwatch-agent.rpm" -o "amazon-cloudwatch-agent.rpm"
+elif [[ "$server_arch" == "aarch64" ]]; then
+  curl "https://amazoncloudwatch-agent.s3.amazonaws.com/amazon_linux/arm64/latest/amazon-cloudwatch-agent.rpm" -o "amazon-cloudwatch-agent.rpm"
+else
+  echo "Unknown server architecture: $server_arch."
+  exit 1
+fi
+
+yum install -y ./amazon-cloudwatch-agent.rpm
+rm amazon-cloudwatch-agent.rpm
+```
+
+3. Update variables.pkrvars.hcl values for source_ami_name_filter_arm64 and source_ami_name_filter_x86_64 as shown below:
+
+```hcl
+source_ami_name_filter_arm64  = "amzn2-ami-hvm-*-arm64-gp2"
+source_ami_name_filter_x86_64 = "amzn2-ami-hvm-*-x86_64-gp2"
+```
