Flask-Bootstrap supports delivery via CDN or local resources, configurable at runtime. Upon initialization, Flask-Bootstrap will store a dictionary on your app named yourapp.extensions['bootstrap']['cdns'], which maps names to :py:class:`~flask_bootstrap.CDN` instances.

You can use :py:func:`~flask_bootstrap.bootstrap_find_resource` in your templates as well when using other resources that may be available on CDNs. CDNs can be added by adding new entries to the dictionary mention above.
