 # 👋 Welcome!
 
-In this Labspace, you're going to gain familiarity with Docker and many of its core components. Specifically, you'll get to do the following:
+This Labspace is designed to help you learn about using containers to run your app's dependent services. These might include:
 
-- Learn about the role of containers and images
-- Run containers and build images
-- Learn about Docker's tooling, including Docker Compose, Testcontainers, and Scout
-- Have fun along the way!
+- **Databases** - run [PostgreSQL](https://hub.docker.com/_/postgres), [MySQL](https://hub.docker.com/_/mysql), [Mongo](https://hub.docker.com/_/mongo), and more
+- **Message queues** - run [RabbitMQ](https://hub.docker.com/_/rabbitmq), [Redis](https://hub.docker.com/_/redis), [Kafka](https://hub.docker.com/r/apache/kafka), and more
+- **Cloud emulators** - run [LocalStack](https://hub.docker.com/r/localstack/localstack)
+- And more!
 
-### What's _not_ in this overview?
-
-The new AI-focused aspects of Docker's tooling will not be covered in this overview. That will be covered in another Labspace.
+The goal is to learn how to use containers to enable you and your team to quickly launch these services, configure them, and easily version them.

+In order to run it though for development, you need a database. You'll learn how to launch that in a container, as well as how to add additional developer tools.

-## Your task
-
-Your task is fairly simple - update the website with a new message and containerize the app.
-
-But, in order to make this update and verify it works, you'll need to complete the following tasks:
-
-1. Setup your development environment to run the app
-2. Make the update to site.
-3. Containerize the app and prepare it for deployment
-
-Don't worry! You'll have help all along the way. Let's get to it!
