@axil can you help me with documentation for nested group feature?

@dzaporozhets sure! Have you pushed anything yet?

@axil no I don't have anything ready. I am wondering if you can make a skeleton for it and I will add screenshots and text. Then you just review and improve/extend text. Feel free to ping me on slack

Ok :)
