 ## Introduction
 
-First off this lab is entirely optional and also not for the faint hearted. Gitlab CI is currently introducing components to replace the current templates and openTofu will be updated to that as soon as they are supported in self managed runners. If you're not comfortable experimenting and cleaning things up in AWS manually **don't do this lab**. For this I recommend using the terraform template.

+## Terraform and OpenTofu Labs for AWS
+
+Welcome to the Terraform/Tofu labs for AWS. This set of labs aims to teach you the basics of terraform/tofu, to get you started on your journey. It focuses on deploying resources to AWS (Amazon Web Services) and keeps costs at a minimum.
+
+> [!Note]
+> Don't forget to do the clean up steps after the labs to shut down the infrastructure. 
+
+#### Requirements
+- You'll need an AWS account from [https://aws.amazon.com](https://aws.amazon.com)
+- If you want to do lab 4 you'll need an account at [https://gitlab.com](https://gitlab.com)
+
+It's recommended that you are familiar with the linux command line and bash, however you can just copy and past from the tutorials
+
+### Labs
+
+- [Lab 1](./1-getting-started/README.md) - Will get you setup with the tooling and show you the basic commands
+- [Lab 2](./2-simple-example/README.md) - Will introduce you to variables
+- [Lab 3](./3-remote-states/README.md) - Will help you create and setup remote states using dynamoDB and S3
+- [Lab 4](./4-gitlab-ci/README.md) - Will walk you through setting up a Gitlab CI/CD pipeline with Terraform (tofu coming soon)
+
+### Links
+
+- [Terraform](https://terraform.io)
+- [OpenTofu](https://opentofu.org/)
+
+### Trouble Shooting
+
+#### No Space left on device
+If you experience and issue like below on your CloudShell you'll need to delete any **unused** ```terraform.tfstate``` and ```terraform.tfstate.backup``` in previous directories.
+
+![no space left on disk](./img/no-space.png)
+
+> [!Note]
+> Make sure you have run terraform destroy before deleting on-disk state files, otherwise you'll need to manually delete resources in the AWS console to avoid charges!
