 Special thanks to [Sjoerd Langkemper](https://github.com/Sjord) who has provided a strong base to start off from https://github.com/Sjord/growatt_api_client
 These projects may merge in the future since they are simmilar in code and function.
 
+This library supports both the classic password-based API and the token-based V1 API, officially supported by Growatt. Currently, the V1 API implementation supports MIN and SPH devices, where MIN broadly corresponds to classic TLX and SPH to classic MIX. If your inverter supports the V1 API, it is encouraged to use this over the classic API, as it offers better security, more features, and more relaxed rate limiting.

 ## Noah Settings
+
 The noah settings function allow you to change individual values on your noah system e.g. system default output power, battery management, operation mode and currency
 From what has been reverse engineered from the api, each setting has a `setting_type` and a set of `parameters` that are relevant to it.
 
 Known working settings & parameters are as follows (all parameter values are strings):
+
 * **Change "System Default Output Power"**
   * function: `api.update_noah_settings`
   * setting type: `default_power`
