+# Dittofeed Piece for ActivePieces
+
+This piece provides integration with [Dittofeed](https://dittofeed.com/), a customer data platform for user analytics and tracking.
+
+## Authentication
+
+To use the Dittofeed piece, you need to provide:
+
+1. **API Key**: Your Dittofeed API key for authentication
+2. **Base URL**: The base URL of your Dittofeed instance (e.g., `https://api.dittofeed.com` or your self-hosted instance URL)
+
+## Actions
+
+### Identify User
+
+Identify a user in Dittofeed with their unique ID and traits.
+
+**Parameters:**
+- **User ID** (required): A unique identifier for the user
+- **User Traits** (optional): An object containing user properties like name, email, etc.
+
+**Example:**
+```json
+{
+  "userId": "user123",
+  "traits": {
+    "name": "John Doe",
+    "email": "john@example.com",
+    "plan": "premium"
+  }
+}
+```
+
+### Track Event
+
+Track a user event in Dittofeed.
+
+**Parameters:**
+- **User ID** (required): A unique identifier for the user
+- **Event** (required): The name of the event to track
+- **Properties** (optional): An object containing event properties
+
+**Example:**
+```json
+{
+  "userId": "user123",
+  "event": "purchase_completed",
+  "properties": {
+    "product": "Premium Plan",
+    "price": 99.99,
+    "currency": "USD"
+  }
+}
+```
+
+### Screen View
+
+Track a screen view event in Dittofeed.
+
+**Parameters:**
+- **User ID** (required): A unique identifier for the user
+- **Name** (required): The name of the screen viewed
+- **Properties** (optional): An object containing screen view properties
+
+**Example:**
+```json
+{
+  "userId": "user123",
+  "name": "checkout_page",
+  "properties": {
+    "referrer": "product_page",
+    "device": "mobile"
+  }
+}
+```
+
+## Troubleshooting
+
+### Common Errors
+
+1. **Authentication failed**: Check that your API key is correct and has the necessary permissions.
+2. **API endpoint not found**: Verify that your base URL is correct and points to a valid Dittofeed instance.
+3. **Rate limit exceeded**: You've made too many requests in a short period. Wait and try again later.
+4. **Invalid input**: Ensure that your User ID is not empty and that traits/properties are valid objects.
+
+### Best Practices
+
+1. Use consistent User IDs across all actions to ensure proper user tracking.
+2. Keep event names consistent and descriptive for better analytics.
+3. Include relevant properties with events and screen views to capture valuable context.
