Tutorial to ramda-cli, a jq-like JSON processor for command-line

In this tutorial we'll use ramda-cli with [GitHub's Repos API][gh-repos-api] to get a list of @jeresig's most starred repos.

[ramda-cli][ramda-cli] is a command-line tool for processing JSON using functional pipelines. As the name suggests, its utility comes from [Ramda][ramda] and [the wide array of functions][ramda-docs] it provides for operating on lists and collections of objects. It also employs
