Terminal is disabled. Unable to type the command for installing Jekyll. I'm working on windows. Is it necessary to have Linux/Mac to install Jekyll?
No. you use it on codeacademy's website by typing gem install jekyll into the terminal.
gem install jekyll
But how do I enter to the terminal to write my code?
Seems that the terminal does not work in Chrome Browser. I found it works in Firefox. Amazing that a organisation that teaches web dev as it's core audience can't manage cross-browser compatibility.
