The following contains a list of links to various HTML, pdf, and zip files with the mirt package, often generated using R markdown via the knitr package and hosted on Github. This wiki is intended as an extension to the mirt JSS publication (Chalmers, R. P. (2012). mirt: A Multidimensional Item Response Theory Package for the R Environment. Journal of Statistical Software, 48, 1-29), which is now largely out of date. Nevertheless, appreciate the citations whenever the package is used!
