+# About IaC Foundations
+
+The IaC Foundations component is focused on:
+
+- Teaching you the considerations to think about when coming up with your foundational Terraform/OpenTofu and Terragrunt patterns
+- Giving you a fully configured set of git repositories with an initial folder structure
+
+## What's included
+
+- **Strategy.** We recommend core patterns your Terragrunt and Terraform/OpenTofu git repo needs to incorporate to scale effectively.
+- **IaC Modules.** No IaC modules are needed for this component.
+- **Tooling.** We recommend Terragrunt to effectively use Terraform/OpenTofu at scale.
+- **Setup.** We grant you access to a sophisticated git repo template that includes customization options and generates your repo code.
+- **Updates.** We publish ongoing updates to IaC foundational patterns and will write [patches](/patcher) if applicable to adopt those changes.
+
+## IaC foundations considerations
+
+When creating your initial Terraform/OpenTofu and Terragrunt infrastructure, there are a number of patterns you need to consider how to solve, including:
+
+- How to create the backend (e.g. S3 bucket) for storing Terraform state
+- How to structure your folder hierarchy
+- How to handle tagging and labels
+- Whether to use branches per environment
+- How to handle global variables
+- How to handle module default values
+
+This component includes either pre-baked implementations that address these considerations, or written guidance on how to incorporate them yourself.

+# Initial setup
+
+To set up IaC Foundations, we use three pre-configured git repository templates that include best practices and also allow for customization.
+
+For each repository below, navigate to the template repository and select **Use this template** -> **Create a new Repository**. This will initiate repository creation. You should select your org as the owner, add a description if you like, make sure you are creating a **private** repo, and click **Create repository**.
+
+The repository template will be created, and you can follow the instructions in the `README` to bootstrap your IaC Foundations. Gruntwork is available to assist with questions around other patterns as they arise.
+
+### Infrastructure Live Template
+
+_[https://github.com/gruntwork-io/infrastructure-live-template](https://github.com/gruntwork-io/infrastructure-live-template)_
+
+This template creates an infrastructure-live repository with scaffolding for a best practices Terragrunt configuration, including patterns for module defaults, global variables, and account baselines. It also configures Gruntwork Pipelines, which is easy to remove if you don't want it.
+
+### Infrastructure Modules Template
+
+_[https://github.com/gruntwork-io/infrastructure-modules-template](https://github.com/gruntwork-io/infrastructure-modules-template)_
+
+This template creates an empty infrastructure-modules repository that will be used to store Terraform/OpenTofu modules that your organization has authored and intends to use within your organization.
+
+### Infrastructure Pipelines Template
+
+_[https://github.com/gruntwork-io/infrastructure-pipelines-template](https://github.com/gruntwork-io/infrastructure-pipelines-template)_
+
+This template is only necessary if you plan on implementing [Gruntwork Pipelines](../pipelines).
