+
+### Mistral API Key

+You can get your Mistral API Key there: <https://docs.mistral.ai/#api-access>.
+
+#### As an environment variable
+
+Just set the `MISTRAL_API_KEY` environment variable.
+
+#### As a client argument
+
+```rs
+use mistralai_client::v1::client::Client;
+
+fn main() {
+    let api_key = "your_api_key";
+
+    let client = Client::new(Some(api_key), None, None, None);
+}
+```
+
+## Usage
+
+### Chat without streaming
+
+```rs
+use mistralai::v1::{
+    chat_completion::{
+        ChatCompletionMessage, ChatCompletionMessageRole, ChatCompletionRequest,
+        ChatCompletionRequestOptions,
+    },
+    client::Client,
+    constants::OPEN_MISTRAL_7B,
+};
+
+fn main() {
+    // This example suppose you have set the `MISTRAL_API_KEY` environment variable.
+    let client = Client::new(None, None, None, None);
+
+    let model = OPEN_MISTRAL_7B.to_string();
+    let messages = vec![ChatCompletionMessage {
+        role: ChatCompletionMessageRole::user,
+        content: "Just guess the next word: \"Eiffel ...\"?".to_string(),
+    }];
+    let options = ChatCompletionRequestOptions {
+        temperature: Some(0.0),
+        random_seed: Some(42),
+        ..Default::default()
+    };
+
+    let chat_completion_request = ChatCompletionRequest::new(model, messages, Some(options));
+    let result = client.chat(chat_completion_request).unwrap();
+    println!("Assistant: {}", result.choices[0].message.content);
+    // => "Assistant: Tower. [...]"
+}
