How to create sub theme of Twitter bootstrap..?

I was able to create a sub theme using the following .info file. Create this plus the tweaks.css file and you should be good to go.

name = subtheme
description = Twitter bootstrap subtheme
version = 0.1
core = 7.x
base theme = twitter_bootstrap

regions[header]         = 'Top Bar'
regions[highlighted]    = 'Highlighted'
regions[help]           = 'Help'
regions[content]        = 'Content'
regions[sidebar_first]  = 'Primary'
regions[sidebar_second] = 'Secondary'
regions[footer]         = 'Footer'

stylesheets[all][] = tweaks.css

settings[toggle_name] = 0
settings[toggle_search] = 1

i have created a new subtheme (folder, with themename.info file)

in themename.info

name = subtheme
description = Twitter bootstrap subtheme
version = 0.1
core = 7.x
base theme = twitter_bootstrap

regions[header]         = 'Top Bar'
regions[highlighted]    = 'Highlighted'
regions[help]           = 'Help'
regions[content]        = 'Content'
regions[sidebar_first]  = 'Primary'
regions[sidebar_second] = 'Secondary'
regions[footer]         = 'Footer'

stylesheets[all][] = tweaks.css

settings[toggle_name] = 0
settings[toggle_search] = 1

after activate it:

Basetheme should be bootstrap the error should go away then

First copy bootstrap_subtheme folder and put into theme folder then change name of folder which u want.

After change info file name themename.info.

In info file change name and description.

then clear cache.

I'm not sure I understand where to copy bootstrap_subtheme folder: I found that folder in sites/all/themes/bootstrap/bootstrap_subtheme. In a typical subtheming operation I would expect to copy the bootstrap_subtheme into the sites/all/themes folder, & then change the folder name, etc. as described in #8. Is there a typo in #8 : should it refer to themes folder instead of theme folder??

Thx, Jeff
