Http tutorial skips over essential steps

[Kilian]

The tutorial on https://github.com/evancz/guide.elm-lang.org/blob/master/architecture/effects/http.md is not self-contained and tripped me up for a number of reasons.

• does not mention you need to add Import Http, for that you need to look at the online example
• it is not explained you need to install the http module first
• the name to use for the http module is not self-evident for people looking at the tutorial. I tried elm-lang/http, elm-http and http before asking in Slack. I suppose other users would just abandon the guide. The previous page introduces new imports but they do not require additional installs.

"evancz/elm-http" is not a logical name and it, alongside how to install it, should be mentioned in the tutorial.

A quick mention on top of phase two of "by the way, the http module is located here, and you need to install and import it" would be a good idea so people do not have to look elsewhere to get their local example working.

I ran into the same issue, both with HTTP and Json

Yeah, this guide needs a revamp, it should be more like MDN where you can contribute and even translate... Next big step... Wish I knew enough to start moving it myself

I was able to fill in the missing steps by first installing the elm-lang/http package

$ elm-package install elm-lang/http

And then by adding these imports at the top of the file:

import Http
import Json.Decode as Json

This is also a duplicate of this issue: https://github.com/evancz/guide.elm-lang.org/issues/21 and addressed by this PR (opened Sept 2016 with no response).

The new version of the book includes all the examples in full!
