 #### Specifying query parameters when navigating
 
 In order to specify query parameters when navigating to a new route, use either `navigator.push_with_query` or
-the `navigator.replace_with_query` functions. It uses `serde` to serialize the parameters into a query string for the URL so
-any type that implements `Serialize` can be passed. In its simplest form, this is just a `HashMap` containing string

+the `navigator.replace_with_query` functions. It uses the `ToQuery` trait to serialize the parameters into a query string for the URL. The `ToQuery` trait is automatically implemented for `serde` so any type that implements `Serialize` can be passed. In its simplest form, this is just a `HashMap` containing string pairs. In more complex scenarios the `ToQuery` trait can be implemented manually for a custom query format.
 
 #### Obtaining query parameters for the current route
