Default docs page doesn't show much helpful about xray

[fireproofsocks]

I understand the bewilderment, but this is normal functionality for ExDocs (you can see the "tabs" for Pages and Modules). Alternatively, you can specify dedicated markdown pages to be the default -- that's useful if you want to include guides or how-tos, but otherwise it's just a summary. Generally, the habit to get into with Elixir packages is to get familiar with navigating the modules -- that's where all the functions are documented. Sometimes it seems like you've stepped into an empty house (and sometimes projects are undocumented), but a lot of times you have to click thru to the modules. It can be frustrating, and I didn't really have an appreciation for the organization until I had to wander through the Erlang docs, and I could see how much Elixir has improved on that.

I've added the README to the docs and published v1.2.0 so the landing page is a nicer handoff.
