Think of it like
Launch template = employee ID badge design. ASG = HR that keeps 2–10 servers alive.

- Do local lab
Deep explanation
Layman words first, then technical detail — read slowly

Example (Doonops)
Modern HCL — names are examples, not from any third-party course
Example HCL
# see project files
Terraform runs on your computer — copy this HCL into a folder, then follow the local lab steps below.

Project files for this lab
Full implementation folder — copy all files, then run terraform commands
Lab project files (full folder)
Copy every file below into one folder — same as a real repo module. Then run the local lab steps.
Suggested folder: Suggested path: ~/doonops-terraform/17-asg/
