Going to defer to @jessieay or someone else more familiar with the project on this one. If Foreman is used in all environments, it seems that the entire line can be removed from CONTRIBUTING. If it's only used for development, I think it's fine for the project to be opinionated and say "run this project in development using Foreman", and just having Foreman in the development group of the Gemfile.

/cc #179

[plemiszki]

Yes, that's probably true. I removed the line. The gem is used in production however, so I didn't move it to the development group.

Looks good to me! Will wait on @jessieay to merge.

@plemiszki you're right, foreman is used in prod. That comment in CONTRIBUTING is from a boilerplate rails app setup that didn't use foreman in production. Mind removing

If you don't have foreman, see Foreman's install instructions. It is purposefully excluded from the project's Gemfile.

while we're here?

thanks for the pR!

@jessieay sorry for the delay. I have removed the comment. Please let me know if everything looks ok now.

there was a merge conflict so I pulled your branch down and made a few tweaks before merging. Merged at a2f6a0f - thank you very much!!
