Welcome to #rubyonrails

Please behave in a polite, considerate and inclusive manner in the channel at all times. People volunteer their time in the channel to help people like you with your Rails problems and some respect (in both directions) will go an extremely long way.

These rules are in place so that you can get the quickest and best support from #rubyonrails.

Rule #0: Show rather than tell. Explaining your problem with code, stacktraces or errors is always preferred to explaining it with just text. Show us what's happening, rather than telling us.

1. Do your research before hand. Your question may be answerable with a quick Google search or by simply experimenting. If you're using a method in Rails, look it up in the API Docs or in the Official Guides.
2. If you've tried Googling, explain what terms you've tried to use so people can better help you.

# Hello, and welcome to makefile basics.
#
# You will learn why `make` is so great, and why, despite its "weird" syntax,
# it is actually a highly expressive, efficient, and powerful way to build
# programs.

# Once you're done here, go to

# problem: when presenting, I want to obscure
# my prompt to act like it's at root of file system 
# and be very basic with no git info, etc.

# solution: this theme lets you set a ENV to the path 
# of your presentation, which will help remove unneeded prompt
# features while in that path 

# oh-my-zsh theme for presenting demos
# based off the default rubbyrussell theme
