-Now that your BeeAI Platform is up and running, and you have a basic understanding of how to run the agent via either the GUI or CLI, let’s get to some coding.
+Now that your BeeAI Platform is up and running, and you know how to run an agent via the GUI or CLI, it’s time to create your first agent.
 
-To build an agent that automatically appears in the platform, all you need to do is use the BeeAI SDK library, which handles the registration process for you.
-
-Although building a “Hello World” agent is straightforward, we’ve streamlined the process for you with a starter repository that you can begin editing right away.
+With the BeeAI SDK, you can build an agent that automatically registers with the platform — no extra setup required.
 
+To make things even easier, we’ve provided a starter repository. You can clone it and start coding immediately, so you can focus on your agent logic instead of boilerplate setup.

 ## Starting from Scratch
 
-Want to build your agent without using our starter repo?  
-
-All you need to do is set up an empty Python project, install `beeai-sdk` as a dependency, and then use the code above.
+If you prefer not to use the starter repo:
+- Create an empty Python project
+- Install `beeai-sdk`
+- Copy the example code above
 
-There’s no magic in the starter repo. It simply provides some basic Python scaffolding, a simple GitHub workflow, and a Dockerfile, most of which are entirely optional.
+The starter repo mainly provides basic scaffolding, a GitHub workflow, and a Dockerfile — all optional.
 
 ## Next Steps
 
-Now that you've built your Hello World agent, you can:
-- Explore how to provide more [GUI configuration](/build-agents/agent-details) options through the concept of `AgentDetail`
-- Leverage [LLM Access](/build-agents/llm-access) in your agent
-- Understand how [Messages](/build-agents/messages) are used for communication between Agent and the Client
-- Build beautiful GUI for your agents with [GUI Components](/build-agents/gui-components)
-- Request structured input from the user using [forms](/build-agents/forms)
-- Learn how to work with [files](/build-agents/files)
-- [Share your agent](/how-to/share-agents) with the others
