Adding new alfresco 4.x theme

When we want to create our own custom theme in alfresco we need to modify only few things.

I tried using alfresco 4.2.x

#1.  Go to below location and add your new theme.

<alfresco_home>\tomcat\webapps\share\WEB-INF\classes\alfresco\site-data\themes
or
<alfresco_home>\tomcat\shared\classes\alfresco\web-extension\site-data\themes


#2. Copy Existing Theme and modify them.

<alfresco_home>\tomcat\webapps\share\themes


Modify all css / images accordingly.

Thats it....!!!
