-To run, the project expects secret keys from a `.env` file. Locally set up this `.env` file. You require connection to an LLM, an embedding provider, and API keys for the Langfuse integration.

+To run, the project expects secret keys from a `.env` file. Locally set up this `.env` file. You require an `AWS_ACCESS_KEY_ID` and an `AWS_SECRET_ACCESS_KEY` to make connection to Amazon Bedrock LLMs and embedding models. Furthermore, API keys for the Langfuse integration are needed. The latter you can acquire after setting up a Langfuse project in the Langfuse GUI, either through a local setup or via Langfuse Cloud.
 
 Here how the `.env` file should look like:
 
 ```
 # .env 
-LLM_API_KEY= # Your LLM API key
+# AWS keys
+AWS_ACCESS_KEY_ID= # Your AWS access key
+AWS_SECRET_ACCESS_KEY= # Your AWS secret access key
 
 # Langfuse credentials
 LANGFUSE_PUBLIC_API_KEY= # Your Langfuse public API key
