 # cIRT
 An R Package detailing the Choice Item Response Theory Model
+
+
+# Install Instructions (All platforms)
+To install the `cIRT` package, there are two options: CRAN (stable) or GitHub (Developmental).
+
+The installation process with CRAN is the simplest
+```r
+install.packages("cIRT")
+```
+
+Prior to installing with `devtools`, please make sure to have a compiler installed on your system that is compatible with R.
+
+If you have a compiler already installed, then continue on by installing the package dependencies and finally the package itself by doing the following: 
+
+```r
+# Install dependencies
+install.packages("RcppArmadillo")
+
+# Install the package from github
+devtools::install_github("tmsalab/cIRT")
+```
