+## Cloudformation
+
+<https://adamtheautomator.com/aws-cli-cloudformation/> (example of deploying an S3 bucket with static site `index.html`.)
+
+To create a cloudformation template you should create a `template.yaml`. This yaml file should have at the top:
+
+```yaml
+AWSTemplateFormatVersion: 2010-09-09
+Description: A simple CloudFormation template
+```
+
+Then you should add a `Resources` key and populate this with all the infrastructure you need to provision.
+
+### Creating templates
+
+Documentation for all AWS resources is: <https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-template-resource-type-ref.html>.
+
+A good approach is to use the GUI to create an object, and then lookup the cloudformation template as you go along.
+
+### Deploy a stack/template
+
+To deploy, you should run the command: `aws cloudformation deploy --template-file template.yaml --stack-name static-website`
+
+### Failure
+
+If something goes wrong, you can use `describe-stack-events` and pass the `stack-name` to find the events leading up to the failure: `aws cloudformation describe-stack-events --stack-name strapi-s3`.
+
+If this is the first time you are creating a stack you will not be able to re-deploy the stack. You must first delete the stack entirely and then re-deploy with any fixes.
+
+You can delete a stack by running: `aws --profile admin cloudformation delete-stack --stack-name strapi-s3`.
+
+### Stacks
+
+<https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/stacks.html>
+
+A cloudformation stack is a collection of AWS resources that you can manage as a single unit. You can group different resources under one stack then create, update or destroy everything under this stack.
+
+Using stacks means AWS will treat all resources as a single unit. They must all be created or destroyed successfully to be created or deleted. If a resource cannot be created, Cloudformation will roll the stack back to the previous configuration and delete any interim resources that were created.
+
+### Snippets
+
+#### Deploy a template/stack
+
+`aws --profile admin cloudformation deploy --template-file ./01-stack-storage.yaml --stack-name strapi-s3`
+
+#### Destroy a stack
+
+`aws --profile admin cloudformation delete-stack --stack-name strapi-s3`
+
+## Tags
+
+Suggested tags for all AWS resources are:
+
+| Tag         | Description                        | Example                  |
+| ----------- | ---------------------------------- | ------------------------ |
+| git         | git repo that contains the code    | `web-dev`                |
+| owner       | who the resource is for/owned      | `home`, `work`, `elliot` |
+| project     | what project it belongs to         | `strapi-elb`             |
+| test        | flag for a temporary test resource | `true`                   |
+| environment | environment resource belongs to    | `dev`, `prod`            |
+| deployment  | AWS tool used for deployment       | `cloudformation`, `elb`  |
+
+### Cloudformation
+
+For Cloudformation resources the following tags get applied automatically:
+
+| Tag                           | Description                     | Example                                                                                            |
+| ----------------------------- | ------------------------------- | -------------------------------------------------------------------------------------------------- |
+| aws:cloudformation:stack-name | stack-name of the resource      | `strapi-s3`                                                                                        |
+| aws:cloudformation:logical-id | resource name given in template | `ELBExampleBucket`                                                                                 |
+| aws:cloudformation:stack-id   | ARN of the cloudformation stack | arn:aws:cloudformation:eu-west-1:745437999005:stack/strapi-s3/459ebbf0-88aa-11ea-beac-02f0c9b42810 |

 # To Do
 
-Finish S3 config for env vars
-Deploy to AWS and ensure vars are working
+~~Finish S3 config for env vars~~
+~~Deploy to AWS and ensure vars are working~~
 
 Use cloudformation to deploy bucket instead of tieing it to the RDS instance.
 Use <https://strapi.io/documentation/3.0.0-beta.x/deployment/amazon-aws.html#_2-create-the-bucket> for bucket options for the template.
