+## Dynamic Dispatch for Different Providers
+
+For any struct that implements `Config` trait, you can wrap it in a smart pointer and cast the pointer to `dyn Config`
+trait object, then your client can accept any wrapped configuration type.
+
+For example,
+
+```rust
+use async_openai::{Client, config::Config, config::OpenAIConfig};
+
+let openai_config = OpenAIConfig::default();
+// You can use `std::sync::Arc` to wrap the config as well
+let config = Box::new(openai_config) as Box<dyn Config>;
+let client: Client<Box<dyn Config> > = Client::with_config(config);
+```
