+# HarperDB Data Loader
+
+This directory contains YAML or JSON files that are automatically loaded into your HarperDB database tables when your application starts.
+
+## How It Works
+
+1. Place data files in this directory with `.yaml`, `.yml`, or `.json` extensions
+2. Files are processed when HarperDB starts
+3. Records are inserted/updated based on file modification time:
+   - New records are always added
+   - Existing records are only updated if the file's modification time is newer than the record's stored timestamp
+   - Records with timestamps newer than the file's modification time are preserved unchanged
+
+## File Format
+
+Data files must contain `table` and `records` fields. The `database` field is optional.
+
+### JSON Example
+
+```jsonc
+{
+  "database": "dev",       // Optional - uses default database if omitted
+  "table": "Product",      // Required - name of the table
+  "records": [             // Required - array of records
+    {
+      "id": "1",           // Primary key field
+      "name": "Laptop",
+      "price": 999.99
+    }
+  ]
+}
+```
+
+### YAML Example
+
+```yaml
+database: dev              # Optional - uses default database if omitted
+table: products            # Required - name of the table
+records:                   # Required - array of records
+  - id: 1                  # Primary key field
+    name: "Laptop"
+    price: 999.99
+```
+
+## Key Features
+
+- **Automatic Table Creation**: Tables are created if they don't exist
+- **Schema Inference**:
+  - The system will automatically infer a schema from the first record when creating a new table
+  - The `id` field is automatically detected as the primary key
+  - It's preferred to define the schema explicitly in your application, but this provides a quick start
+- **File Modification Time**:
+  - The data loader uses the file's modification time (`mtime`) to determine if records should be updated
+  - "Touching" a file (updating its modification time) will force a reload of its data
+- **Multi-file Support**: You can have multiple data files for different tables
+- **Complex Data Types**: Supports nested objects, arrays, and various data types
+- **One Table Per File**: Each file should define one table
+
+## Tips for Managing Data
+
+- To force a reload of data, simply update the file's modification time:
+  ```bash
+  # Update the file's timestamp using touch
+  touch data/products.json
+  ```
+- If you need to restore to previous data, you can replace the file and update its timestamp
+- The system automatically handles the comparison between file modification time and record timestamps
