-## Example:
+## Usage
+The library needs to be configured with your account's secret key, which is available on the website. We recommend setting it as an environment variable. Here's an example of initializing the library with the API key loaded from an environment variable and creating a completion:
+
+### Set OPENAI_API_KEY to environment variable
 ```bash
-export OPENAI_API_KEY={YOUR_API_KEY}
+$ export OPENAI_API_KEY=sk-xxxxxxx
 ```
 
-### Chat
+### Create client
+```rust
+use openai_api_rs::v1::api::Client;
+use std::env;
+let client = Client::new(env::var("OPENAI_API_KEY").unwrap().to_string());
+```
+
+### Create request
+```rust
+use openai_api_rs::v1::chat_completion::{self, ChatCompletionRequest};
+let req = ChatCompletionRequest {
+    model: chat_completion::GPT4.to_string(),
+    messages: vec![chat_completion::ChatCompletionMessage {
+        role: chat_completion::MessageRole::user,
+        content: String::from("Hello OpenAI!"),
+    }],
+};
+```
+
+### Send request
+```rust
+let result = client.completion(req).await?;
+println!("{:?}", result.choices[0].text);
+```
