+"""An entry-recording functionality designed to be used as the memory of an agent.
+
+This module provides the foundational class needed for storing information in the memory of an agent.
+Then objective is to implement a very simple and efficient system that can be used for any agent and
+for any kind of information (an entry). The user defines the capacity of the memory chooses the format
+of the entries, which allows for a greater flexibility.
+
+Features:
+
+- Capacity-based short-term memory, with a FIFO system.
+- Efficient storage and retrieval of entries.
+- Support for different entry types of entries.
+- Possibility to send entries to other agents.
+
+For now, the module contains only one main component:
+- Memory: A class representing the memory of an agent.
