Needs GettingStarted/docs/intro

[KirillOsenkov]

Would be great to have a simple Getting Started - what is this repo for, what scenarios are enabled, sample code on how to consume the bits.

For instance I'd like to have an API that allows me to download the .pdb file given the input .dll file and the path to the symbol server. I know symchk does it, but I want control over where the .pdb is placed on disk. I'm not clean if this repo/library can solve my problem and if yes, how do I use it. What's the .dll name or Nuget package that I should reference to use the library? What's the simplest Program.cs code snippet that does something?

Thanks!
