+# Overlays
+Below is a list of all the overlays and what they called them. These can also be found in `OverlayManager.hpp`. Feel free to
+contribute to this list!
+
+Each overlay is tied to an index which is used to access the overlay in two different arrays:
+- `data_0203e0e8`: maps the overlay index to the original ID.
+- `data_02043c88`: maps the overlay index to its internal name (which is how we know how their names).
