 ## Introduction
 
 ### Purpose of the Document
 
-This document provides guidelines and instructions for users looking to implement Terraform module for managing Aurora cluster and SQL Server RDS instance.
+This document provides guidelines and instructions for users looking to create and manage Security Groups
 
 ### Module Overview
 
-The [terraform-aws-arc-db](https://github.com/sourcefuse/terraform-aws-arc-db) module provides a secure and modular foundation for managing Aurora cluster and SQL Server RDS instances.
+The Terraform AWS ARC Security Group module create and manage AWS security groups with customizable ingress and egress rules for secure network traffic control.
 
 ### Prerequisites
 
 Before using this module, ensure you have the following:
 
 - AWS credentials configured.
 - Terraform installed.
-- A working knowledge of AWS Aurora cluster and SQL Server RDS instance.
+- A working knowledge of AWS VPC, security grouo, and Terraform concepts.

 ### Integration with Existing Terraform Configurations
 
+Refer to the Terraform Registry for the latest version.
+
+## Integration with Existing Terraform Configurations
 Integrate the module with your existing Terraform mono repo configuration, follow the steps below:
 
-1. Create a new folder in `terraform/` named `db`.
-2. Create the required files, see the [examples](https://github.com/sourcefuse/terraform-aws-arc-db/tree/main/examples/rds) to base off of.
-3. Configure with your backend
-  - Create the environment backend configuration file: `config.<environment>.hcl`
-    - **region**: Where the backend resides
-    - **key**: `<working_directory>/terraform.tfstate`
-    - **bucket**: Bucket name where the terraform state will reside
-    - **dynamodb_table**: Lock table so there are not duplicate tfplans in the mix
-    - **encrypt**: Encrypt all traffic to and from the backend

 ## Module Usage
 
 ### Basic Usage
 
-For basic usage, see the [example](https://github.com/sourcefuse/terraform-aws-arc-db/tree/main/examples/rds) folder.
+For basic usage, see the [example](https://github.com/sourcefuse/terraform-aws-arc-security-group/tree/main/example) folder.
 
 This example will create:
 
-- RDS Instance Example
-This example demonstrates deploying a single RDS instance using the module, configuring an Amazon RDS database with basic settings like instance class, storage, and connectivity. It showcases options for database engine, encryption, and CloudWatch monitoring for a standalone RDS database. Ideal for simple, production-ready RDS setups.
-
-### RDS Proxy
-
-For RDS Proxy, see the [example](https://github.com/sourcefuse/terraform-aws-arc-db/tree/main/examples/rds-proxy) folder.
-
-- RDS Proxy Example
-This example configures an RDS Proxy for an RDS database, helping manage connection pooling for improved database performance and security. By integrating with RDS Proxy, it reduces connection management overhead and scales automatically with demand, useful for applications with variable database traffic and sensitive to scaling requirements.
+This Terraform module creates a security group with the following configurations:
 
-### Aurora Cluster
+Ingress Rules:
 
-For Aurora Cluster, see the [example](https://github.com/sourcefuse/terraform-aws-arc-db/tree/main/examples/aurora) folder.
+- VPC Traffic: Allows all TCP traffic within the VPC (0-65535) based on the VPC CIDR block.
+- Self-Traffic: Allows all TCP traffic (0-65535) within the same security group for self-referencing communication.
+- Source Security Group: Permits TCP traffic (0-65535) from a specific source security group.
 
-- Aurora Cluster Example
-This example provisions an Amazon Aurora cluster, utilizing the module to set up a high-availability, high-performance database solution. The configuration includes multiple instances within a cluster, providing a resilient and cost-effective solution suitable for demanding applications.
+Egress Rules:
 
-### Aurora Cluster Serverless
-
-For Aurora Cluster Serverless, see the [example](https://github.com/sourcefuse/terraform-aws-arc-db/tree/main/examples/aurora-serverless) folder.
-
-- Aurora Serverless Cluster Example
-This example deploys an Aurora Serverless cluster autoscaling, making it ideal for applications with unpredictable or intermittent database usage. The module configures serverless capacity, connectivity, and database settings, automatically adjusting to workload needs without manual intervention.
+- Outbound Traffic: Allows unrestricted outbound traffic (0.0.0.0/0) for all protocols and ports.
 
 ### Tips and Recommendations
 
-The module focuses on provisioning Aurora database cluster and Amazon RDS instance for SQL Server. Adjust the configuration parameters as needed for your specific use case.
+The module can manage egress rules to security groups, S3 endpoints, and more.
