Closed Unassigned: Composite C1, Bootstrap and less [1698]

Hi,
I want to change the theme and appearance of Composite site using Bootstrap option (there is another option?)
All step by step, for example: http://docs.composite.net/Getting-started/Starter-sites/Twitter-Bootstrap/Bootstrap-Sample-Themes and http://docs.composite.net/Getting-started/Starter-sites/Twitter-Bootstrap/Bootstrap-Theming makes reference to the folder "~/Frontend/Styles/bootstrap/2.3.1/".

What I am doing wrong? Why my site doesn't have this folder? I have to create it manually?
I've seen videos and also have the folder "~/Frontend/Styles/bootstrap/2.3.1/"

Here, http://community.composite.net/Blog/2012/08/17/Say-hello-to-Twitter-Bootstrap, it is another step by step where appears the folder.
Thanks in advance
Comments: To use bootstrap and less install a new 4.0 site and select one of the "Cph" options.
