## Quick Start

<Steps>
  <Step title="Create Agent Router">
    ```rust theme={"theme":{"light":"vitesse-light","dark":"vitesse-dark"}}
    use praisonai::{Agent, when};

    // Create specialized agents
    let tech_agent = Agent::new()
        .name("Tech Support")
        .instructions("Help with technical issues")
        .build()?;

    let sales_agent = Agent::new()
        .name("Sales")
        .instructions("Handle sales inquiries")
        .build()?;

    let support_agent = Agent::new()
        .name("Support")
        .instructions("General customer support")
        .build()?;

    // Create router with conditions
    let router = when(|input: &str| input.contains("API") || input.contains("error"))
        .then(tech_agent)
        .when(|input: &str| input.contains("price") || input.contains("buy"))
        .then(sales_agent)
        .otherwise(support_agent);

    router.run("I need help with an API error").await?;
    // Routes to tech_agent
    ```
  </Step>
</Steps>
