+# This streamlit demonstration is meant to simulate two types of memory within cognitive architecture:
+# Each time we remember a moment, we construct it anew.
+# We use the building blocks of Episodic Memory which is recall of feelings of being somewhere.
+# We also use Semantic Memory which is concrete knowledge about our world and about our personal history.
+# With Episodic Memory, its purpose is to provide us with coherence connecting events.  In Episodic Memory, accuracy is less important than consistency.
+# In order to have a strong sense of self, it is important that our memories fit with our beliefs and feelings about ourselves.
