README tweaks

[ehershey]

The examples are super helpful and this makes them easier to run.

Hi Ernie and thanks for your help!

You'll have to be patient with us as we haven't yet sorted out how we want to deal with contributions so it may take a little while to accept your pull request.

[ehershey]

Okay, no problem. Thanks for replying! There are a handful of other changes I'd probably also contribute if there's a way to do it.

@ehershey Actually your post has reminded me, providing you're happy to license your contribution under the MPL 2.0 - the license for all the Pulse authored source code in the repository, we're happy to accept your contribution.

[ehershey]

Yep, fine with me! Do I need to do that formally somehow?

[ndavidson-pulse]

Nope we should be good with your commentary on this issue.

Hello @ehershey,
maybe you can add contactable and contactErr as return values, because with version 8.3 this is required.

Hello @ndavidson-pulse and @pillalamarriramana,
can you please accept the pull request. Since the current instructions in your main readme.md no longer work?
