 ## Usage
 
+### Prerequisites
+
+To use this SDK, ensure you have the following prerequisites:
+
+- Foundry Local must be installed and available on the PATH
+- Rust 1.70.0 or later
+
+### Create a new Rust project:
+
+```bash
+cargo new hello-foundry-local
+cd hello-foundry-local
+```
+
+### Install crates
+
+Install the following Rust crates using Cargo:
+
+```bash
+cargo add foundry-local anyhow env_logger serde_json
+cargo add reqwest --features json
+cargo add tokio --features full
+```
+
+Alternatively, you can add these dependencies manually to your `Cargo.toml` file.
+
+```toml
+[dependencies]
+anyhow = "1.0.98"
+env_logger = "0.11.8"
+foundry-local = "0.1.0"
+reqwest = { version = "0.12.19", features = ["json"] }
+serde_json = "1.0.140"
+tokio = { version = "1.45.1", features = ["full"] }
+```
+
+### Update the `main.rs` file
+
+Replace the contents of `src/main.rs` with the following code to create a simple application that interacts with the Foundry Local service:
+
 ```rust
 use foundry_local::FoundryLocalManager;
 use anyhow::Result;
 
 #[tokio::main]
 async fn main() -> Result<()> {
     // Create a FoundryLocalManager instance with default options
-    let manager = FoundryLocalManager::new("phi-3.5-mini", true).await?;
+    let mut manager = FoundryLocalManager::builder()
+        .alias_or_model_id("phi-3.5-mini") // Specify the model to use   
+        .bootstrap(true) // Start the service if not running
+        .build()
+        .await?;
 
     // Use the OpenAI compatible API to interact with the model
     let client = reqwest::Client::new();
-    let response = client.post(&format!("{}/chat/completions", manager.endpoint()))
+    let endpoint = manager.endpoint()?;
+    let response = client.post(&format!("{}/chat/completions", endpoint))
         .header("Content-Type", "application/json")
         .header("Authorization", format!("Bearer {}", manager.api_key()))
         .json(&serde_json::json!({
-            "model": manager.get_model_info("phi-3.5-mini").await?.id,
+            "model": manager.get_model_info("phi-3.5-mini", true).await?.id,
             "messages": [{"role": "user", "content": "What is the golden ratio?"}],
         }))
         .send()
         .await?;
-    
+
     let result = response.json::<serde_json::Value>().await?;
     println!("{}", result["choices"][0]["message"]["content"]);
 
     Ok(())
 }
 ```
 
-## Installation
+### Run the application
 
-Add the following to your `Cargo.toml`:
+To run the application, execute the following command in your terminal:
 
-```toml
-[dependencies]
-foundry-local = "0.1.0"
+```bash
+cargo run
 ```
