- **Understanding Configuration Files**: Learn the structure of Terraform configuration files, including `main.tf`, `variables.tf`, `outputs.tf`, and `terraform.tfvars`.

- **Providers**: Understand how providers work and how to configure them (AWS, Azure, GCP, etc.).



### [3. **Terraform Language Deep Dive**](./03-Terraform-Language-Deep-Dive.md)



- **Terraform Configuration Language (HCL)**: Master the HashiCorp Configuration Language (HCL), focusing on syntax, expressions, and data types.

- **Variables**: Learn how to define and use variables, including variable types, default values, and input variables.

- **Outputs**: Understand how to use outputs to pass information between modules or display useful information.

- **Data Sources**: Learn how to fetch information from other parts of your infrastructure.

- **Resource Lifecycle**: Understand the lifecycle of resources in Terraform, including `create`, `read`, `update`, and `delete` operations.



### [4. **Terraform State Management**](./04-Terraform-State-Management.md)



- **State Files**: Learn how Terraform uses state files to map real-world resources to your configuration.

- **Backend Configuration**: Understand different backend types (local, remote) and how to configure them.

- **State Locking**: Explore the concept of state locking to prevent race conditions.

- **State Management Commands**: Commands like `terraform state`, `terraform refresh`, and `terraform import`.



### [5. **Terraform Modules**](./05-Terraform-Modules.md)



- **What are Modules?**: Understand the purpose and benefits of using modules in Terraform.

- **Creating and Using Modules**: Learn how to create reusable modules, structure your code, and use existing modules from the Terraform Registry.
