+1 Yes, I was wondering how this was exposed. Didn't realize the examples are only on gh-pages.

@vanchi-zendesk Are you suggesting that I should also create an examples directory in the master radar branch, and refer to it from the README.md here: https://github.com/zendesk/radar#documentation ?

I did briefly consider doing this, but then thought that having a sample directory and an examples directory might create more confusion than clarity. In the documentation link and anchor above, we do point to the to tutorial early.

I have no problem duplicating the examples code in both branches, if you think that will be helpful.

No, this is fine. As long as there is a way to get at it :-D
