@ -31,5 +31,35 @@ If you're completely new to Terraform, we recommend reading the
the examples. However, due to the intuitive configuration Terraform
uses it isn't required.
## Examples
All of the examples are in the
["examples" directory within the Terraform source code](https://github.com/hashicorp/terraform/tree/master/examples). Each example (as well as the examples
directory) has a README explaining the goal of the example.
To use these examples, Terraform must first be installed on your machine.
You can install Terraform from the [downloads page](/downloads.html).
Once installed, you can use two steps to view and run the examples.
To clone any examples, run `terraform init` with the URL to the example:
```
$ terraform init github.com/hashicorp/terraform/examples/aws-two-tier
...
```
This will put the example files within your working directory. You can then
use your own editor to read and browse the configurations. This command will
not _run_ any code.
If you want to run the example, just run `terraform apply`:
```
$ terraform apply
...
```
Terraform will interactively ask for variable input and potentially
provider configuration, and will start executing.
When you're done with the example, run `terraform destroy` to clean up.
