Update Getting Started

Right now the Getting Started section in the README is a bit outdated.

People who are just getting started with this library are not likely to have all of the dependencies needed (latest version of VS, .NET Core, etc.) to compile the source code and demo application.

I am looking for people newer to this project to either comment or submit a PR with suggestions on how to improve this.

Some ideas to consider:

• Getting started section so that it is as simple as possible for someone new to the library.
• Consider including a link to my examples repo
• Consider moving up the link to the releases page with the pre-compiled demo app from the See It In Action section
• Remove the Source Code section and instead simply link over to the wiki page

Esamina le sezioni Getting Started, See It In Action e Building the Source del README, insieme alla pagina wiki collegata Compiling From Source. Aggiorna le istruzioni per iniziare in modo che i prerequisiti e la demo precompilata siano facili da trovare, e assicurati che le istruzioni per la compilazione dal codice sorgente rimandino alla wiki; il lavoro è completato quando una persona alle prime armi può seguire il percorso documentato senza informazioni di configurazione obsolete.
