Thanks for writing and posting it. It looks useful. Like it says on the cover, it is about how to deploy Elixir to various cloud hosts such as Digital Ocean. There is not much about actual Elixir programming, but that is fine, it doesn't claim to have that.

I like that it is under a CC license. It's slightly unfortunate that the pdf is 27MB. Do you think of releasing whatever "source code" you generated it from? Can I ask what you used? (Maybe it says inside someplace, but I haven't examined the book closely yet). It would be nice if it were in a git repo or wiki somewhere, so that people could send updates as the Elixir and hosting ecosystems change.

I haven't yet used Elixir and one of my not-so-happy memories of using Erlang was that while the language and base libs were themselves well documented, in order to get anything done you had to know the whereabouts of a lot of community resources such as git repos, plus figure out various bits of deployment magic. This book will at least help with the latter.
