So many issues with Cmder, setting up Ruby.

I'm going through the Jason Seifer Ruby class and working along side the "Installing a Ruby on Rails Development Environment in Windows". Everything with the Cmder application gives me errors. I've looked up a few of the errors and resolved them (I think!), but I still don't see the same command prompt on mine as Jason's does.

For instance, his looks like this: C:\Users\Jason Seifer {git} {lamb}

Mine looks like: C:\users\bcede_000 (then a character that looks like the Cmder logo here)

I'm at the point of installing git by typing: -> git config --global user.name The result is an error saying "git: The term 'git' is not recognized as the name of a cmdlet, function, script file, or operable program..."

I'm not sure what I'm doing wrong, so hoping somebody can help.
