 ## Key Features
-
+- `Impersonate`: The `Client` offers an `impersonate` option, enabling it to mimic web browsers by replicating their headers and `TLS/JA3/JA4/HTTP2` fingerprints. This feature is crucial for avoiding detection as a bot and potential blocking by websites.
+- `Thread-safe`: The `Client` is designed to be thread-safe, allowing it to be safely used in multithreaded environments.
 - `High Performance`: The attributes of the `Response` object are executed in Rust, which is known for its high performance. This ensures that operations like accessing headers, decoding text, or parsing JSON are very fast.
 - `Lazy Execution`: All attributes of the `Response` object are executed lazily. This means that the actual computation or data retrieval happens only when you access the attribute, not when the `Response` object is created.
 - `Automatic Character Encoding Detection`: The `Response` object intelligently detects the character encoding of the response body from the "Content-Type" header. If the encoding is not specified, it defaults to "UTF-8".

 #### Client Methods
 
 The `Client` class provides a set of methods for making HTTP requests: `get`, `head`, `options`, `delete`, `post`, `put`, `patch`, each of which internally utilizes the `request()` method for execution. The parameters for these methods closely resemble those in `httpx`.
