I've installed RSpec on a win7 lappy (2009 HP i3)
Ruby 2.2.5p319 (2016-04-26 revision 54774) [i386-mingw32]
Rspec 3.5.4
RubyGem 2.6.7
Bundler version 1.13.1
I am following along with the http://rspec.info/ homepage tutorial videos to make sure everything works. If I am reading the "bowling' demo correctly bin/rspec --format doc should run the specification test file?

Is this specific to a 'Nix system?
I've mimicked the directory structure:/bin/
bundler
htmldiff
ldiff
rspec
/lib/
bowling.rb
/spec/
bowling_spec.rb
spec_helper.rb
...and while in the parent project directory when I enter bin/rspec --format doc in PowerShell I get a system window prompt for a text editor:

I'm confused - should I be seeing the Rspec test file results? (I really want to bask in the joy that is green!)

Should I be doing something to this file?
...and rspec does work correctly on my win7 system, but I am confused by the http://rspec.info/ homepage tutorial.
Apologies if this is a really dumb question, I just want to make sure that I'm not missing something or using RSpec incorrectly.
