+# Overview
+
+```
+Module Name:  Epom DSP Bid Adapter
+Module Type:  Bidder Adapter
+Maintainer: [email protected]

+
+# Integration Guide for Publishers
+
+## Basic Configuration
+
+Here is an example configuration for integrating the Epom DSP Bid Adapter into your Prebid.js setup.
+
+### Sample Banner Ad Unit
+
+```javascript
+var adUnits = [
+  {
+    code: 'epom-banner-div', // Ad slot HTML element ID
+    mediaTypes: {
+      banner: {
+        sizes: [
+          [300, 250], 
+          [728, 90]
+        ] // Banner sizes
+      }
+    },
+    bids: [
+      {
+        bidder: 'epomDsp', // Adapter code
+        params: {
+          endpoint: 'https://your-epom-endpoint.com/bid', // Epom DSP endpoint
+        }, 
+          adUnitId: 'sampleAdUnitId123', // Unique Ad Unit ID
+          bidfloor: 0.5, // Minimum bid floor (optional)
+      }
+    ]
+  }
+];
+```
+
+---
+
+# Params
+
+Below are the parameters that can be configured in the `params` object for the **Epom DSP Bid Adapter**.
+
+| Parameter      | Type     | Required | Description                                                                 |
+|----------------|----------|----------|-----------------------------------------------------------------------------|
+| `endpoint`     | string   | Yes      | The URL of the Epom DSP bidding endpoint.                                   |
+| `adUnitId`     | string   | No       | Unique identifier for the Ad Unit.                                          |
+| `bidfloor`     | number   | No       | Minimum CPM value for the bid in USD.                                       |

+
+---
+
+# Global Settings (Optional)
+
+You can define global configuration parameters for the **Epom DSP Bid Adapter** using `pbjs.setBidderConfig`. These settings will apply to all requests made via the adapter.
+
+### Example Global Configuration
+
+```javascript
+pbjs.setBidderConfig({
+  bidders: ['epomDsp'],
+  config: {
+    epomSettings: {
+        endpoint: 'https://your-epom-endpoint.com/bid', // Epom DSP endpoint
+    }
+  }
+});
+```
+
+---
+
+# Response Format
+
+The **Epom DSP Bid Adapter** complies with the OpenRTB protocol and returns responses in the following format:
+
+```json
+{
+  "bids": [
