The CRE is a Wordpress plugin which activates both Scripture references and
references to the Catechism of the Catholic Church, showing non-intrusive
popups when you mouseover them. No awkward wrapper syntax is required.
References in old posts and pages are automatically activated.
The CRE can be installed just like any normal Wordpress plugin: simply move the
unpacked contents of this package into a directory called "catholic-reference"
under your Wordpress plugin directory. The plugin directory is normally
/wordpress-root/wp-content/plugins, where /wordpress-root is the directory
where Wordpress is installed.
If you did not download the full CRE package which also contains the texts
(Bible and Catechism), then you must go to
http://blog.purepistos.net/index.php/cre/
and download the texts separately from there. The CRE will not function
without the texts.
