+# Terraform
+
+This directory holds the terraform modules for maintaining your complete persistent infrastructure.
+
+Prerequisite: install the `jq` JSON processor: `brew install jq`
+
+## Initial setup
+
+1. Manually run the bootstrap module following instructions under `Terraform State Credentials`
+1. Setup CI/CD Pipeline to run Terraform
+  1. Copy bootstrap credentials to your CI/CD secrets using the instructions in the base README
+  1. Create a cloud.gov SpaceDeployer by following the instructions under `SpaceDeployers`
+  1. Copy SpaceDeployer credentials to your CI/CD secrets using the instructions in the base README
+1. Manually Running Terraform
+  1. Follow instructions under `Set up a new environment` to create your infrastructure
+
+## Terraform State Credentials
+
+The bootstrap module is used to create an s3 bucket for later terraform runs to store their state in.
+
+### Bootstrapping the state storage s3 buckets for the first time
+
+1. Run `terraform init`
+1. Run `./run.sh plan` to verify that the changes are what you expect
+1. Run `./run.sh apply` to set up the bucket and retrieve credentials
+1. Follow instructions under `Use bootstrap credentials`
+1. Ensure that `import.sh` includes a line and correct IDs for any resources created
+1. Run `./teardown_creds.sh` to remove the space deployer account used to create the s3 bucket
+
+### To make changes to the bootstrap module
+
+*This should not be necessary in most cases*
+
+1. Run `terraform init`
+1. If you don't have terraform state locally:
+    1. run `./import.sh`
+    1. optionally run `./run.sh apply` to include the existing outputs in the state file
+1. Make your changes
+1. Continue from step 2 of the boostrapping instructions
+
+### Retrieving existing bucket credentials
+
+1. Run `./run.sh show`
+1. Follow instructions under `Use bootstrap credentials`
+
+#### Use bootstrap credentials
+
+1. Add the following to `~/.aws/credentials`
+    ```
+    [notify-terraform-backend]
+    aws_access_key_id = <access_key_id from bucket_credentials>
+    aws_secret_access_key = <secret_access_key from bucket_credentials>
+    ```
+
+1. Copy `bucket` from `bucket_credentials` output to the backend block of `staging/providers.tf` and `production/providers.tf`
+
+## SpaceDeployers
+
+A [SpaceDeployer](https://cloud.gov/docs/services/cloud-gov-service-account/) account is required to run terraform or
+deploy the application from the CI/CD pipeline. Create a new account by running:
+
+`./create_service_account.sh -s <SPACE_NAME> -u <ACCOUNT_NAME>`
+
+## Set up a new environment manually
+
+The below steps rely on you first configuring access to the Terraform state in s3 as described in [Terraform State Credentials](#terraform-state-credentials).
+
+1. `cd` to the environment you are working in
+
+1. Set up a SpaceDeployer
+    ```bash
+    # create a space deployer service instance that can log in with just a username and password
+    # the value of < SPACE_NAME > should be `staging` or `prod` depending on where you are working
+    # the value for < ACCOUNT_NAME > can be anything, although we recommend
+    # something that communicates the purpose of the deployer
+    # for example: circleci-deployer for the credentials CircleCI uses to
+    # deploy the application or <your_name>-terraform for credentials to run terraform manually
+    ./create_service_account.sh -s <SPACE_NAME> -u <ACCOUNT_NAME> > secrets.auto.tfvars
+    ```
+
+    The script will output the `username` (as `cf_user`) and `password` (as `cf_password`) for your `<ACCOUNT_NAME>`. Read more in the [cloud.gov service account documentation](https://cloud.gov/docs/services/cloud-gov-service-account/).
+
+    The easiest way to use this script is to redirect the output directly to the `secrets.auto.tfvars` file it needs to be used in
+
+1. Run terraform from your new environment directory with
+    ```bash
+    terraform init
+    terraform plan
+    ```
+
+1. Apply changes with `terraform apply`.
+
+1. Remove the space deployer service instance if it doesn't need to be used again, such as when manually running terraform once.
+    ```bash
+    # <SPACE_NAME> and <ACCOUNT_NAME> have the same values as used above.
+    ./destroy_service_account.sh -s <SPACE_NAME> -u <ACCOUNT_NAME>
+    ```
+
+## Structure
+
+Each environment has its own module, which relies on a shared module for everything except the providers code and environment specific variables and settings.
+
+```
+- bootstrap/
+  |- main.tf
+  |- providers.tf
+  |- variables.tf
+  |- run.sh
+  |- teardown_creds.sh
+  |- import.sh
+- <env>/
+  |- main.tf
+  |- providers.tf
+  |- secrets.auto.tfvars
+  |- variables.tf
+```
+
+In the environment-specific modules:
+- `providers.tf` lists the required providers
+- `main.tf` calls the shared Terraform code, but this is also a place where you can add any other services, resources, etc, which you would like to set up for that environment
+- `variables.tf` lists the variables that will be needed, either to pass through to the child module or for use in this module
+- `secrets.auto.tfvars` is a file which contains the information about the service-key and other secrets that should not be shared
+
+In the bootstrap module:
+- `providers.tf` lists the required providers
+- `main.tf` sets up s3 bucket to be shared across all environments. It lives in `prod` to communicate that it should not be deleted
+- `variables.tf` lists the variables that will be needed. Most values are hard-coded in this module
+- `run.sh` Helper script to set up a space deployer and run terraform. The terraform action (`show`/`plan`/`apply`/`destroy`) is passed as an argument
+- `teardown_creds.sh` Helper script to remove the space deployer setup as part of `run.sh`
+- `import.sh` Helper script to create a new local state file in case terraform changes are needed
