 AWS CloudFormation is AWS's primary Infrastructure-as-Code (IaC) service. It is used to declaratively define your architecture on the AWS cloud, including resources such as S3 Buckets, Lambda Functions, and much more.
 
-CloudFormation **Stack** templates are written in either YAML or JSON and can be written manually or generated by higher-level tools such as [AWS CDK]( {{< ref "docs/integrations/aws-cdk" >}} ), [Pulumi]({{< ref "docs/integrations/pulumi" >}}) or [Serverless Framework]( {{< ref "docs/integrations/serverless-framework" >}}).

+CloudFormation **Stack** templates are written in either YAML or JSON and can be written manually or generated by higher-level tools such as [AWS CDK]( {{< ref "docs/integrations/aws-cdk" >}} ), [AWS SAM]( {{< ref "docs/integrations/aws-sam" >}}) [Pulumi]({{< ref "docs/integrations/pulumi" >}}) or [Serverless Framework]( {{< ref "docs/integrations/serverless-framework" >}}).
 
 ## Quickstart
 
 In this quickstart guide we will deploy a simple CloudFormation stack consisting of a single S3 Bucket.
 
 ### Prerequisites
 
-- [`docker`](https://docs.docker.com/get-docker/)
-- [`docker-compose`](https://docs.docker.com/compose/install/)
-- [`awslocal`]({{< ref "aws-cli#localstack-aws-cli-awslocal" >}})
+Make sure you've set up [`awslocal`]({{< ref "aws-cli#localstack-aws-cli-awslocal" >}}) and that you have a running LocalStack instance.
 
-### Deploy a stack to LocalStack
-
-#### 1. Start an instance of LocalStack via Docker
-
-In general you need to at least include **S3** and **IAM** in addition to your other services when starting your LocalStack instance.
-We are doing this here by setting the `SERVICES` environment variable.
-
-```yaml
-# content of ./docker-compose.yml
-version: "3.8"
-
-services:
-  localstack:
-    container_name: "cfn_quickstart_localstack_main"
-    image: localstack/localstack
-    network_mode: bridge
-    ports:
-      - "127.0.0.1:53:53"
-      - "127.0.0.1:53:53/udp"
-      - "127.0.0.1:443:443"
-      - "127.0.0.1:4566:4566"
-      - "127.0.0.1:4571:4571"
-    environment:
-      - SERVICES=cloudformation,s3,iam
-
-```
-
-```bash
-# start the container
-docker-compose up -d
-
-# check if all services have started (look for a line reading "Ready.")
-docker-compose logs
-
-# check if all required services are up
-# the output should include:  {"s3": "running", "iam": "running"}
-curl http://localhost:4566/health
-```
-
-#### 2. Write and deploy a simple CloudFormation stack
