+# Mem0 Context Provider Examples
+
+[Mem0](https://mem0.ai/) is a self-improving memory layer for Large Language Models that enables applications to have long-term memory capabilities. The Agent Framework's Mem0 context provider integrates with Mem0's API to provide persistent memory across conversation sessions.
+
+This folder contains examples demonstrating how to use the Mem0 context provider with the Agent Framework for persistent memory and context management across conversations.
+
+## Examples
+
+| File | Description |
+|------|-------------|
+| [`mem0_basic.py`](mem0_basic.py) | Basic example of using Mem0 context provider to store and retrieve user preferences across different conversation threads. |
+| [`mem0_sessions.py`](mem0_sessions.py) | Example demonstrating different memory scoping strategies with Mem0. Covers user-scoped memory (memories shared across all sessions for the same user), agent-scoped memory (memories isolated per agent), and multiple agents with different memory configurations for personal vs. work contexts. |
+| [`mem0_oss.py`](mem0_oss.py) | Example of using the Mem0 Open Source self-hosted version as the context provider. Demonstrates setup and configuration for local deployment. |
+
+## Prerequisites
+
+### Required Resources
+
+1. [Mem0 API Key](https://app.mem0.ai/) - Sign up for a Mem0 account and get your API key - _or_ self-host [Mem0 Open Source](https://docs.mem0.ai/open-source/overview)
+2. Azure AI project endpoint (used in these examples)
+3. Azure CLI authentication (run `az login`)
+
+## Configuration
+
+### Environment Variables
+
+Set the following environment variables:
+
+**For Mem0 Platform:**
+- `MEM0_API_KEY`: Your Mem0 API key (alternatively, pass it as `api_key` parameter to `Mem0Provider`). Not required if you are self-hosting [Mem0 Open Source](https://docs.mem0.ai/open-source/overview)
+
+**For Mem0 Open Source:**
+- `OPENAI_API_KEY`: Your OpenAI API key (used by Mem0 OSS for embedding generation and automatic memory extraction)
+
+**For Azure AI:**
+- `FOUNDRY_PROJECT_ENDPOINT`: Your Azure AI project endpoint
+- `FOUNDRY_MODEL`: The name of your model deployment
+
+## Key Concepts
+
+### Memory Scoping
+
+The Mem0 context provider supports scoping via identifiers:
+
+- **User scope** (`user_id`): Associate memories with a specific user, shared across all sessions
+- **Agent scope** (`agent_id`): Isolate memories per agent persona
+- **Application scope** (`application_id`): Associate memories with an application context
