+# CAN Error TUI
+
+This is a Tangible User Interface program designed to track CAN Errors including their count, recency, description, and name.
+
+Users can:
+
+- Acknowledge the error (Hide and resets the error until it is sent again)
+- Ignore the error (Hides, resets, and stops reading all future occurrences of the error)
+- View ignored errors and choose to unignore those errors
+
