Support people who installed Elm through npm without the -g flag?

[ento]

Elm commands need to be prefixed with ./node_modules/.bin if you didn't install Elm globally.

• Introduction.md: ./node_modules/.bin/elm-repl
• Getting Started.md: PATH=./node_modules/.bin:$PATH node_modules/.bin/elm-repl

(or do export PATH=path/to/node_modules/.bin:$PATH before working on stuff)

options

• Make a note on how to fix it in the teacher guide Add teacher guide to prompt instructors  #22
• Add a troubleshooting section

I worry about this tutorial being in the business of debugging common issues — there are a lot of things that can go wrong. That said, I like the idea of a troubleshooting guide, just want to make sure there isn't scope creep.

Tagging this as an enhancement

Using RailsBridge as a model, their InstallFest documentation is fantastic. Very well organized, with detailed, platform-specific instructions, and troubleshooting tips for seemingly every possible issue. I think this would be a great eventual target for handling such issues.
