add readme instruction for locally serving the documentation

[c-nv-s]

Please could you add a note to the readme on how to serve the documentation locally for when users are offline

overal docs need to be improved, they don't explain how to use any of the components. we need examples, even if its a codesandbox example on each page...

Hi @tan-ahmed,

I'm working on this part to add variety of examples for each docs page.

Cheers, Sajad
