Add description to the commands

Hi!

First of all, thanks for the amazing plugin!

Is it possible to add description for the commands, so that we can see more details in which key?

Take a look how we see vim-table-mode mappings in which-key:

@ronisbr Thanks for the suggestion, i'll take a look how we could do this. Typically, so far I have been leaning towards the documentation.
