-Description: This package facilitates embedding solutions within an `rmarkdown`
-    document that can later be given to students.
+Description: Writing homework assignments for students in the age of 'RMarkdown' 
+    necessitates the creation of two separate documents -- assign.Rmd and soln.Rmd.
+    The goal of assignr is to create one document main.Rmd that can be broken
+    apart into the above two documents. Thus, there is no longer a need to copy
+    and paste between the assign and the soln documents as all of the contents
+    are together in one file.
 Depends:
     R (>= 3.3.0)
