I feel a little bit uneasy about "... questions *the team* will have ..." -- makes it sounds like the rest of the community isn't quite involved.

How about something like: "... which includes some questions that we'd like you to answer in order to help the community/others understand your contribution and expedite the pull request reviewing process."

Also, "The contents of this file **should** be ..." -- a little bit more assertive so it doesn't sound like it's optional.

Also, I just had 2 thoughts:

1) Wondering if including a picture of the PR template pasted into a PR will help so its 100% clear.
2) We don't really tell them that this only applies to **new** IA pull requests -- perhaps we should do that?

@mwmiller What do you think?
