+## File Descriptions
+
+- **main.tf**: Contains the main configuration for creating the Azure Traffic Manager profile and its associated resources.
+- **variables.tf**: Defines the input variables used in the Terraform configuration.
+- **provider.tf**: Configures the Azure provider to interact with Azure resources.
+- **terraform.tfvars**: Provides default values for the variables defined in `variables.tf`.
+- **outputs.tf**: Defines the outputs such as Traffic Manager profile ID and FQDN.
+
+## Variables
+
+Below is a list of variables used in this template, their expected values, types, and examples:

+| `dns_name`              | The relative DNS name for the Traffic Manager profile | string       | `"mytmprofile"`      |
+| `ttl`                   | The DNS Time-To-Live (TTL) in seconds                | number       | `30`                 |
+| `monitor_protocol`      | The protocol used for endpoint monitoring             | string       | `"HTTP"`             |
+| `monitor_port`          | The port used for endpoint monitoring                 | number       | `80`                 |
+| `monitor_path`          | The path used for endpoint monitoring                 | string       | `"/"`                |
+
+## Usage
+
+1. Clone the repository and navigate to the traffic-manager directory.
+2. Update the `terraform.tfvars` file with your values.
+3. Initialize and apply the Terraform configuration:
+
+```bash
+terraform init
+terraform plan
+terraform apply
+```
+
+## Outputs
+
+| Output Name                | Description                                 |
+|----------------------------|---------------------------------------------|
+| `traffic_manager_profile_id` | The ID of the Traffic Manager profile      |
+| `traffic_manager_fqdn`       | The FQDN of the Traffic Manager profile    |
