This tutorial assumes you have a running TYPO3 CMS-installation 7.6 and want to install themes with theme_bootstrap. If you use TYPO3 CMS 6.2, this will run perfect, but please be sure to fetch the corresponding versions of the extensions.
1. Step: Install and activate extensions
First of all you have to install the following extensions:
- css_styled_content - Alternatively (not additional) you can choose fluid_styled_content and then add the static-template: Themes (Experimental: Additional add this for fluid_styled_content). But please be aware that at the moment theme_bootstrap with fluid_styled_content is not working perfectly for all content-elements.
Please activate these extensions. Then go to the Module "Template" - "Edit the whole template record"
2. Step: Choose a theme for Root-Page
Then go to the "Page"-Module, choose your Root-Page in the page-tree and edit the "page-properties". At the tab "Behaviour" choose "Use as a Root-page". After you have done this you will see a little themes-icon at your root-page in the page-tree.
Please go to the Themes-Module and choose a theme. In case you installed theme_bootstrap only, activate it now.
3. Step: Choose backend-layouts
Please go to "Page"-Module and choose your root-Page and page-properties again. In the tab "Appearance" you can choose one of the backend-layouts for your root-page and another one for the subpages.
4. Step: Configuration
Please go to the "Themes"-Module again, choose your root-Page, select "Basic" and set your basic Configuration for colors, baseURL and so on. For further configuration you can choose "Advanced" and "Expert" so you will a lot of constants to choose.
Now you have a TYPO3-installation with bootstrap-layout. For any changes at the templates, additional constants or css/less-changes we recommend not to do any changes at the bootstrap-theme. Instead you should build a child-theme for these changes.
