+# Memory Map
+
+To not have to allocate a ton of things at run time the Standard Library uses a static memory map for some purposes
+
+## Overview
+
+| Address Range | Use |
+| ---- | ---- |
+| `0x0:0x15` | Reset Vector |
+| `0x16:0xFF` | Zero |
+| `0x100:(user code end)` | User Code |
+| `(User code end + 1):0xFFFF` | Library Code |
+| `0xXXF0_0000:0xXXFF_FFFF` | Stack |
+
+## Zero Page
+Some values are needed not often enough to get their own special register, but often enough that it makes sense to keep them at a quickly accessible location.
+This is what the zero page is for. its position in memory allows us to load them into a register with a single instruction.
