# Installing Terraform
> Learn how to install Terraform, a tool for managing infrastructure as code, on a Linux system.
In this lesson, you'll learn how to install Terraform—a powerful tool for managing infrastructure as code. Terraform is distributed as a single binary that you can download from the official [Terraform website](https://www.terraform.io/downloads.html). Once downloaded, simply place the executable in your system's PATH and verify the installation by checking its version.
Terraform supports Windows, macOS, and a range of Linux distributions. For the purposes of this lesson, all examples and labs will use Terraform version 0.13 on a Linux machine.
This lesson uses Terraform v0.13. Ensure you download the correct version for your operating system.
## Installing Terraform 0.13 on Linux
Follow these steps to install Terraform 0.13 on a Linux system:
1. Open your terminal.
2. Download the Terraform 0.13 binary.
3. Unzip the downloaded file.
4. Move the Terraform executable to `/usr/local/bin` so that it is accessible from anywhere.
5. Verify the installation by checking the Terraform version.
Run the following commands:
```bash theme={null}
wget https://releases.hashicorp.com/terraform/0.13.0/terraform_0.13.0_linux_amd64.zip
unzip terraform_0.13.0_linux_amd64.zip
mv terraform /usr/local/bin
terraform version
```
You should see output similar to:
```console theme={null}
Terraform v0.13.0
```
## Working with Terraform
After installing Terraform, you can begin deploying resources using configuration files written in the HashiCorp Configuration Language (HCL). These files have a `.tf` extension and can be edited with any text editor or IDE.
For example, consider the following HCL snippet that defines an AWS EC2 instance resource:
```hcl theme={null}
resource "aws_instance" "webserver" {
ami = "ami-0c2f25c1f66a1ff4d"
instance_type = "t2.micro"
}
```
### Understanding Terraform Resources
A resource in Terraform represents an object managed by the tool. This can range from local files to virtual machines, cloud services, and beyond. Here’s a quick overview of some common resource types:
| Resource Type | Description | Example |
| ------------- | ------------------------ | --------------- |
| EC2 Instance | Virtual machine on AWS | `aws_instance` |
| S3 Bucket | Cloud storage on AWS | `aws_s3_bucket` |
| IAM Role | Access management in AWS | `aws_iam_role` |
Terraform enables you to provision hundreds of resources across multiple cloud providers (such as AWS, GCP, or Azure) as well as manage on-premises infrastructure.
## Getting Started with Simple Resources
In the initial sections of this lesson, we focus on two simple resource types:
* A local file resource.
* A special resource called a random pet.
These examples are designed to help you understand key concepts such as resource lifecycle management and the basics of HCL syntax. Once you have a solid grasp of these fundamentals, you'll be better prepared to deploy more complex, real-world infrastructure scenarios later in the lesson.
With these basic concepts in hand, you're now ready to explore more advanced Terraform configurations and resource management techniques.
