Great question, Matt!
The main thing you want is the component. This is a link straight to version 6.1.5 (the most recent stable version):
joomlabiblestudy.org/invisible-downloads...70%3Acomponent-6.1.5
If you want to display studies as a module (some admins like to do this on the front page, for instance) then you would download and install the module:
joomlabiblestudy.org/invisible-downloads...1-production-release
There are also two plugins we offer.
The first adds searching of your sermons to Joomla's built in search engine:
joomlabiblestudy.org/invisible-downloads...e-study-search-6.1.1
The second provides an automated way to publish an xml file containing links to your sermons. People use this for podcasting - but if you aren't doing that then this plugin won't help you!
joomlabiblestudy.org/invisible-downloads...1-production-release
But again, it's the component you want - all the action takes place there!
