+# PJVM
+PJVM (say PJ-VM as in peanut butter jelly) is a Python based Java Virtual Machine.
+
+## Goal
+The goal of this project is to give an insight into the big and scary Java Virtual Machine.
+
+## Why?
+For the glory of satan of course!
+### No but really?
+I got bored one day and wanted to figure out how the JVM worked. And what better way is there than to just implement it.
