A bit more documentation would be helpful

[Kreyparion]

Hello,

I am a student in Computer Science and I am currently working on a project on an ESN. The objective is to learn the parameters of the input layer and the output layer with a CMA-ES.

I saw the repo and it looked quite promising so I installed the libraries and ran the code on the main branch.
I understood that the aim of this repo is tuning the hyperparameters of the ESN.

First of all, thank you for your code !
I am planning to adapt it for my project. Maybe I could also contribute to it a bit.

So I was wondering if you could add a bit of documentation for the different branches
