+# Memory
+
+In Agents-Flex, memory is divided into two types:
+
+- **ChatMemory**: Used to store conversation content during chat with LLMs.
+- **ContextMemory**: Used in the chain of agents, similar to a Key-Value data structure.
+
+Additionally, Agents-Flex provides default implementation classes for ChatMemory and ContextMemory:
+
+- **DefaultChatMemory**: Default implementation for storing conversation content.
+- **DefaultContextMemory**: Default implementation for the Key-Value data structure.
+
+By default, These implementations are store data in memory. Users can implement custom ChatMemory and ContextMemory for scenarios requiring message persistence.
