lmk if there are any copy adjustments that need to be made

To be honest this looks a bit too advertisy for my taste, especially as Shuttle is calling themselves 'not production ready yet'. I would love to see a small tutorial accompanying this, and maybe a change of tone to 'option of deployment' or such. I think it wouldn't be wise to couple this project too tightly to unrelated hosting projects with their own intransparencies.

@Christoph-AK thanks for the feedback! I've updated the copy a bit to reduce the 'advertisy' appeal and added an example as well. Let me know if this is ok.
