 ## v4-client-js
 The dYdX Chain Client Typescript client is used for placing transactions and querying the dYdX chain.
 
+## v4-client-py
+Python client for dYdX Chain. Huge thanks to [kaloureyes3](https://github.com/kaloureyes3/v4-clients) for helping us
+maintain this!
+
+The library is currently tested against Python versions 3.9, and 3.11.
+
 ## v4-client-cpp (Third Party Client)
+To pull the latest C++ client, run `git submodule update --init --recursive`
+
 This client was originally developed and open-sourced through a grant by the dYdX Grants Trust — an
 unaffiliated and independent third-party from dYdX Trading Inc.
 
 The original client can be found [here](https://github.com/asnefedovv/dydx-v4-client-cpp).

 By clicking the above links to third-party clients, you will leave the dYdX Trading Inc. (“dYdX”) GitHub repository and join repositories made available by third parties, which are independent from and unaffiliated with dYdX. dYdX is not responsible for any action taken or content on third-party repositories.
