-Terraform module which creates RDS resources on AWS.
+This Terraform module provisions an Amazon RDS PostgreSQL database on AWS. Amazon RDS (Relational Database Service) is a managed database service that makes it easy to set up, operate, and scale a relational database in the cloud. This module focuses specifically on PostgreSQL database deployments.
+
+## Features
+
+  1. Creates an Amazon RDS PostgreSQL database with customizable configurations.
+  2. Supports various PostgreSQL versions and allows for easy updates.
+  3. Configurable database instance class, storage capacity, and other PostgreSQL-specific settings.
+  4. Provides options for enabling multi-AZ deployment for enhanced availability and disaster recovery.
+  5. Allows customization of backup retention period and automated backups.
+  6. Supports encryption at rest using AWS Key Management Service (KMS) for enhanced security.
+  7. Enables fine-grained control over network access through security groups and VPC settings.
+  8. Offers customizable tags for resource categorization and management.
