Document build & test

[ashtonmeuser]

Simple docs re: building and testing. Contains info from #282 so opening this as a draft.

Requesting review now that #282 has landed.

This seems like something that should be placed in CONTRIBUTING.md, but what do you think?

[ashtonmeuser]

I think that's your call and is fine either way. Personally, I'd lean to adding it to the README because the addition isn't overly long or detailed and the README is presented to users immediately (on GitHub, NuGet, etc.).

[nuskey8]

In my opinion, README files should be user-oriented documentation. This information is intended for developers and contributors, and is not something that general users need to be aware of.

[ashtonmeuser]

@nuskey8, moved development docs to CONTRIBUTING.md and added a little general guidance preamble.

After thinking about it for a while, I decided that it would be better for me to create a CONTRIBUTING.md file myself, as there are still a few things I'd like to edit and add.

Therefore, I'm sorry, but would it be alright if I closed the pull request?

[ashtonmeuser]

Of course! Happy to see this project get a documentation pass. Closing.
