-    This guide will walk you through the process of getting started with Arcade.dev.  First, we will go over Direct Tool Calling, a simple way to call tools directly from your agent.
+<strong>Build AI agents that actually take action.</strong>
+
+Most AI apps are stuck in read-only mode. Arcade gives your AI the power to act — send Gmail, update Notion, message in Slack, and more.
+
+In this quickstart, you'll:
+* Install the Arcade client
+* Authenticate your first real-world tool
+* Run your first tool call using the arcade client
 
-    Direct tool calling is useful in situations where you already know what tool is needed or when there is no prompt for an LLM to interpret and decide on the tool calling. It also gives you full control over what is executed by the Arcade Engine and how.
+This it's the foundation to build full agents. Real tools. Real actions. Real fast.
