 Normally an atom `theta2` is displayed by Maxima as `{\it theta_2}`. This is problematic as the Greek letter is not rendered as LaTeX `\theta`, and the subscript is in italic which is wrong.  We have fixed this in STACK. Maxima "atoms" with a subscript will be displayed using subscripts.  For example

 ## 1. Set up Moodle.
 
-* Please ensure you have [installed Moodle](http://docs.moodle.org/en/Main_page).  We intend to support STACK within the normal Moodle [release cycle](https://docs.moodle.org/dev/Releases).  STACK has been tested on Moodle 3.8 to 3.10.  STACK is untested on versions before Moodle 3.8.  We intend to support all future Moodle releases. If your version of Moodle is not listed here please contact the developers: we probably simply have not done the testing of future versions yet.  For longer support of older versions of Moodle please contact us, otherwise will will drop them from our list.
