Please update documentation (1. Install global pre-requisites...)

[Kai Toedter]

As first step you wrote in the README.md:
"1. Install global pre-requisites npm install typescript live-server -g"
But you also have both as local devDependencies in your package.json.

So, please remove the initial step from the README.md.

IMHO it is better if we don't have to install any npm packages globally to try out a demo, so my preferred way would be to just keep it in the package.json :)

Updated - thanks.
