 [MARS](http://courses.missouristate.edu/KenVollmar/mars/) is a lightweight interactive

+Developed by Pete Sanderson (psanderson@otterbein.edu) and Kenneth Vollmar (kenvollmar@missouristate.edu).
 
 ## About this project
-__TODO__: Complete project description
+The StackVisualizer tool and application allows the user to view in real time the memory modification operations
+taking place in the stack segment. The user can also observe how the stack grows.
+The address pointed by the stack pointer is displayed in an orange background
+while the whole word-length data in a yellow one. Lower addresses have a grey
+background (given that stack growth takes place form higher to lower addresses).
+The names of the registers whose contents are stored (`sw`, `sh`, `sb` etc.) in the
+stack, are shown in the "Stored Reg" column. In the "Call Layout" column, the subroutine
+frame (activation record) layout is displayed, with subroutine names placed on the highest
+address of the corresponding frames.
