+		1. No copy assignment / constructor are implemented for Client classes. Each object has its own unique Session, WS, and running streams.
 		2. All unique endpoint structs require that the client object contains keys and is not a public client.
 		3. `ClientException` derives from `std::exception` therefore `catch(std::exception)` would also work.
 
 ## REST client
-All REST request methods take a pointer to a `Params` object. This object holds the parameters that would be generated to a query string and sent as the request body.
+All (except for ones that don't have mandatory parameters) REST request methods take a pointer to a `Params` object. This object holds the parameters that would be generated to a query string and sent as the request body.
 <br /> Endpoints that do not require any params, have a default argument which is a `nullptr` (beware if using threads).

+<br />The `stream_manager` method closes a stream when the stream status is set to zero by the `close_stream()` method, or if any other error was encountered (unless `reconnect_on_error` is true).
 <br /> The stream manager also accepts a `bool` for whether or not to ping a listen key periodically. The ping interval is 30 minutes by default, and can be set using `set_refresh_key_interval()` method (in `Client`).
 - #### Custom Streams
 	Custom streams are possible by using `Client`'s `custom_stream()` method. This method accepts 4 arguments: `stream_path` std::string, `buffer` std::string, `functor` functor, and `ping_listen_key` bool (when true, pings listen key periodically).
