-# Hello World Example
-
-Hello World example agent that only returns Message events
-
-## Getting started
-
-1. Start the server
-
-   ```bash
-   uv run .
-   ```
-
-2. Run the test client
-
-   ```bash
-   uv run test_client.py
-   ```
-
-## Build Container Image
-
-Agent can also be built using a container file.
-
-1. Navigate to the directory `samples/python/agents/helloworld` directory:
-
-  ```bash
-  cd samples/python/agents/helloworld
-  ```
-
-2. Build the container file
-
-    ```bash
-    podman build . -t helloworld-a2a-server
-    ```
-
-> [!Tip]  
-> Podman is a drop-in replacement for `docker` which can also be used in these commands.
-
-3. Run you container
-
-    ```bash
-    podman run -p 9999:9999 helloworld-a2a-server
-    ```
-
-## Validate
-
-To validate in a separate terminal, run the A2A client:
-
-```bash
-cd samples/python/hosts/cli
-uv run . --agent http://localhost:9999
-```
-
-
-## Disclaimer
-Important: The sample code provided is for demonstration purposes and illustrates the mechanics of the Agent-to-Agent (A2A) protocol. When building production applications, it is critical to treat any agent operating outside of your direct control as a potentially untrusted entity.
-
-All data received from an external agent—including but not limited to its AgentCard, messages, artifacts, and task statuses—should be handled as untrusted input. For example, a malicious agent could provide an AgentCard containing crafted data in its fields (e.g., description, name, skills.description). If this data is used without sanitization to construct prompts for a Large Language Model (LLM), it could expose your application to prompt injection attacks.  Failure to properly validate and sanitize this data before use can introduce security vulnerabilities into your application.
-
-Developers are responsible for implementing appropriate security measures, such as input validation and secure handling of credentials to protect their systems and users.
