+Submit a job to create a structured export of memories using a customizable Pydantic schema. This process may take some time to complete, especially if you’re exporting a large number of memories. You can tailor the export by applying various filters (e.g., user_id, agent_id, run_id, or session_id) and by modifying the Pydantic schema to ensure the final data matches your exact needs.

+## Introduction to Custom Instructions
+
+Custom instructions allow you to define specific guidelines for your project. This feature helps ensure consistency and provides clear direction for handling project-specific requirements.
+
+Custom instructions are particularly useful when you want to:
+- Define how information should be extracted from conversations
+- Specify what types of data should be captured or ignored
+- Set rules for categorizing and organizing memories
+- Maintain consistent handling of project-specific requirements
+
+When custom instructions are set at the project level, they will be applied to all new memories added within that project. This ensures that your data is processed according to your defined guidelines across your entire project.
+
+## Setting Custom Instructions
+
+You can set custom instructions for your project using the following method:
+
+<CodeGroup>
+```python Code
+# Update custom instructions
+prompt ="""
+Your Task: Extract ONLY health-related information from conversations, focusing on the following areas:

+## Overview
+
+The Memory Export feature allows you to create structured exports of memories using customizable Pydantic schemas. This process enables you to transform your stored memories into specific data formats that match your needs. You can apply various filters to narrow down which memories to export and define exactly how the data should be structured.
+
+## Creating a Memory Export
+
+To create a memory export, you'll need to:
+1. Define your schema structure
+2. Submit an export job
+3. Retrieve the exported data
+
+### Define Schema

+### Retrieve Export
+
+Once the export job is complete, you can retrieve the structured data:
+
+<CodeGroup>
+
+```python Python
+response = client.get_memory_export(user_id="user123")
+print(response)
+```
+
+```bash cURL
+curl -X GET "https://api.mem0.ai/v1/memories/export/?user_id=user123" \
+     -H "Authorization: Token your-api-key"
+```
+
+```json Output
+{
+    "full_name": "John Doe",
+    "current_role": "Senior Software Engineer",
+    "years_experience": 8,
+    "employment_status": "full_time",
+    "education_level": "masters",
+    "skills": ["Python", "AWS", "Machine Learning"]
+}
+```
+
+</CodeGroup>
+
+## Available Filters
+
+You can apply various filters to customize which memories are included in the export:
+
+- `user_id`: Filter memories by specific user
+- `agent_id`: Filter memories by specific agent
+- `run_id`: Filter memories by specific run
+- `session_id`: Filter memories by specific session
+
+<Note>
+The export process may take some time to complete, especially when dealing with a large number of memories or complex schemas.
+</Note>

+You are a graph memory manager specializing in identifying, managing, and optimizing relationships within graph-based memories. Your primary task is to analyze a list of existing relationships and determine which ones should be deleted based on the new information provided.
+Input:
+1. Existing Graph Memories: A list of current graph memories, each containing source, relationship, and destination information.
+2. New Text: The new information to be integrated into the existing graph structure.
+3. Use "USER_ID" as node for any self-references (e.g., "I," "me," "my," etc.) in user messages.

+Guidelines:
+1. Identification: Use the new information to evaluate existing relationships in the memory graph.
+2. Deletion Criteria: Delete a relationship only if it meets at least one of these conditions:
+   - Outdated or Inaccurate: The new information is more recent or accurate.
+   - Contradictory: The new information conflicts with or negates the existing information.
+3. DO NOT DELETE if their is a possibility of same type of relationship but different destination nodes.
+4. Comprehensive Analysis:
+   - Thoroughly examine each existing relationship against the new information and delete as necessary.
+   - Multiple deletions may be required based on the new information.
+5. Semantic Integrity:
+   - Ensure that deletions maintain or improve the overall semantic structure of the graph.
+   - Avoid deleting relationships that are NOT contradictory/outdated to the new information.
+6. Temporal Awareness: Prioritize recency when timestamps are available.
+7. Necessity Principle: Only DELETE relationships that must be deleted and are contradictory/outdated to the new information to maintain an accurate and coherent memory graph.
+
+Note: DO NOT DELETE if their is a possibility of same type of relationship but different destination nodes. 
+
+For example: 
+Existing Memory: alice -- loves_to_eat -- pizza
+New Information: Alice also loves to eat burger.
+
+Do not delete in the above example because there is a possibility that Alice loves to eat both pizza and burger.
