Hi @lukeb-uk, sorry for not getting to this PR for so long. Can I ask why you'd like to limit the responses to just when someone says "Hello."?

I could see actually using this example as being problematic because it would essentially spam your #general channel, but that's not really the intention. The way I see it, the example is meant to illustrate how to use the SDK with as little extra logic as possible. But since I don't expect people to run the example for more than a few seconds to verify that it works, I think its not necessary to filter the messages.

I was just correcting the example to do what the text above it said it was actually doing.
