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Right now the Getting Started section in the README is a bit outdated.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

Revisa las secciones Getting Started, See It In Action y Building the Source del README, junto con la página wiki enlazada Compiling From Source. Actualiza las instrucciones de introducción para que los requisitos previos y la demo precompilada sean fáciles de encontrar, y asegúrate de que las instrucciones para compilar desde el código fuente apunten a la wiki; se considera terminado cuando una persona nueva puede seguir el recorrido documentado sin información de configuración obsoleta.
