Commented 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

Hi,
thanks for your answer.
The article was written for 3.2 but the option Open Cph starter site that indicates is only for 4.0 version.
And then only works for 4.0, begin that in the first step you need to use 4.0. The the following steps are based on 3.2. I'm sorry, but this article is impossible to follow.
Make some thing as simple as change the theme is somewhat difficult to make based on that experience.
Thanks.
