Otherwise, would be good to verify the CLI works if we want to keep this around. I would suggest removing it since it's just another piece to maintain.

Are you looking to have the "Examples of all the commands are below:" section removed only, and what exactly do you want to replace that? What are you referring to with 'PolkadotJS usage'?

@Camnaz I would remove all links to edgeware cli that has to do with the deprecated tool. Unless you are going to support and maintain it long term.
