## What it is
A GitHub Actions JavaScript action that installs a specified version of the Terraform CLI onto the workflow runner and adds it to PATH. It can also configure HCP Terraform/Terraform Enterprise credentials and install a wrapper that exposes terraform stdout, stderr, and exit codes as step outputs.

## Use cases
- install terraform cli in github actions workflow
- pin a specific terraform version in ci
- run terraform plan and apply on pull requests
- configure terraform cloud api token in ci
- capture terraform command output in workflow steps
- automate infrastructure provisioning with github actions

## When to choose
- you use GitHub Actions and need Terraform CLI available in your workflow
- you want automatic credential setup for HCP Terraform or Terraform Enterprise
- you need terraform command outputs (stdout/stderr/exitcode) as workflow step outputs

## When to avoid
- you use GitLab CI, Jenkins, or another CI system instead of GitHub Actions
- you need to install OpenTofu or other Terraform forks
- you run on self-hosted runners without Node.js installed
