| kro works with any Kubernetes resources and CRDs, making it particularly powerful when you need to provision AWS services using ACK controllers while simultaneously creating the necessary Kubernetes resources like secrets, configmaps, and service accounts - all from a single ResourceGraphDefinition that provides a complete, ready-to-use solution. | ||
|
|
||
| kro differs from ACK and Crossplane in its approach to resource management: |

Although this is useful I think we might want to remove it for now
| - **Crossplane** offers comprehensive multi-cloud infrastructure orchestration with composition capabilities | ||
| - **kro** focuses on creating reusable templates that combine multiple resources into cohesive patterns | ||
|
|
||
| In this lab, we'll explore kro's capabilities by first deploying the complete **Carts** application with an in-memory database using a WebApplication ResourceGraphDefinition. We'll then enhance this by composing a WebApplicationDynamoDB ResourceGraphDefinition that builds on the base WebApplication template to add Amazon DynamoDB storage. No newline at end of file |

Carts application = Carts component
Theres a few places throughout the pages to make this same change.

| kro simplifies complex resource management by allowing platform teams to define ResourceGraphDefinitions that encapsulate multiple related resources. Developers interact with simple custom APIs defined by the RGD schema, while kro handles the complexity of creating and managing the underlying resources. | ||

This seems a little out of place being before the install instructions. I'd say move it to the bottom of the page.

| When you create a ResourceGraphDefinition, kro: | ||
|
|
||
| 1. **Registers a new Custom API** - Based on the schema defined in the RGD, kro automatically creates a new Kubernetes API that developers can use |

I would perhaps say "creates a new Kubernetes CRD"
| resourcegraphdefinition.kro.run/web-application created | ||
| ``` | ||
|
|
||
| This registers the WebApplication API. Verify the Custom Resource Definition (CRD): |

I would expand this just a little bit to explicitly mention that kro created the CRD automatically based on the RGD schema.

| Perfect! kro has successfully orchestrated the deployment of all Kubernetes resources required by the carts application as a single unit. |

Probably remove "Perfect!"

I don't think this needs to be an info block, just plain text.
