-Start your LocalStack container using your preferred method using the `LOCALSTACK_ENABLE_BEDROCK=1` configuration variable.
+Start your LocalStack container using your preferred method with or without pre-warming the Bedrock engine.
 We will demonstrate how to use Bedrock by following these steps:
 
 1. Listing available foundation models
 2. Invoking a model for inference
 3. Using the conversation API
 
+### Pre-warming the Bedrock engine
+
+The startup of the Bedrock engine can take some time.
+Per default, we only start it once you send a request to one of the `bedrock-runtime` APIs.
+However, if you want to start the engine when localstack starts to avoid long wait times on your first request you can set the flag `BEDROCK_PREWARM`.

 ### List available foundation models
 
 You can view all available foundation models using the [`ListFoundationModels`](https://docs.aws.amazon.com/bedrock/latest/APIReference/API_ListFoundationModels.html) API.

 You can use the [`InvokeModel`](https://docs.aws.amazon.com/bedrock/latest/APIReference/API_runtime_InvokeModel.html) API to send requests to a specific model.

 ## Limitations
 
-* LocalStack Bedrock implementation is mock-only and does not run any LLM model locally.
+* LocalStack Bedrock currently only officially supports text-based models.
 * Currently, GPU models are not supported by the LocalStack Bedrock implementation.
