+# Integration Instructions
+
+To integrate V-Analytics with your website, follow these steps:
+
+## Step 1: Include the Integration Code
+
+Place the following JavaScript code within your website's HTML to start sending analytics data:
+
+```html
+<script>
+    document.addEventListener('DOMContentLoaded', (event) => {
+        // API endpoint URL
+        const siteKey = 'YOUR_SITE_KEY_HERE'; // Replace with your site's key
+        const apiUrl = `http(s)://<HOST_URL>/analytics/sites/${siteKey}`;
+
+        // Data to send to the API
+        const data = {
+            visitorData: event,
+            siteData: window.location
+        };
+
+        // Options for the fetch request
+        const options = {
+            method: 'POST',
+            headers: {
+                'Content-Type': 'application/json',
+            },
+            body: JSON.stringify(data),
+        };
+
+        // Make the API request
+        fetch(apiUrl, options)
+            .then(response => {
+                if (response.ok) {
+                    console.log('API request succeeded');
+                } else {
+                    error('API request failed');
+                }
+            })
+            .catch(error => {
+                console.error('Error:', error);
+            });
+    });
+</script>
+
+```
+## STEP 2 - Replace 'YOUR_SITE_KEY_HERE'
+
+**Replace 'YOUR_SITE_KEY_HERE' in the code with your actual site's key. This key is provided to you by V-Analytics.**
+
+## Step 3: Include the Code in Your Website
+**Add the provided code snippet to all the pages of your website where you want to track visitor analytics.**
+
+## Step 4: Verify Integration
+
+**Open your website in a browser and check your browser's console for the following messages:**
+
+    "API request succeeded" (if the request is successful).
+    "API request failed" (if there's an issue with the request).
+
+If you see "API request succeeded," your integration is successful, and your website is now sending analytics data to V-Analytics.
+
+If you encounter issues, please refer to the V-Analytics documentation or contact our support for assistance.**
