+# Overview
+
+**Module Name**: adtrgtme Bidder Adapter
+**Module Type**: Bidder Adapter
+**Maintainer**: info@adtarget.me
+
+# Description
+The Adtrgtme Bid Adapter is an OpenRTB interface that support display demand from Adtarget 
+
+# Supported Features:
+* Media Types: Banner 
+* Multi-format adUnits
+* Price floors module
+* Advertiser domains
+
+# Mandatory Bidder Parameters
+The minimal requirements for the 'adtrgtme' bid adapter to generate an outbound bid-request to our Adtrgtme are:
+1. At least 1 banner adUnit 
+2. Your Adtrgtme site id **bidder.params**.**sid**
+
+## Example:
+```javascript
+const adUnits = [{
+    code: 'your-placement',
+    mediaTypes: {
+            banner: {
+                sizes: [[300, 250]]
+            }
+        },
+    bids: [
+        {
+            bidder: 'adtrgtme',
+            params: {
+                sid: 1220291391, // Site/App ID provided from SSP
+            }
+        }
+    ]
+}];
+```
+
+# Optional: Price floors module & bidfloor
+The adtargerme adapter supports the Prebid.org Price Floors module and will use it to define the outbound bidfloor and currency.
+By default the adapter will always check the existance of Module price floor.
+If a module price floor does not exist you can set a custom bid floor for your impression using "params.bidOverride.imp.bidfloor".
+
+```javascript
+const adUnits = [{
+    code: 'your-placement',
+    mediaTypes: {
+        banner: {
+            sizes: [
+                [300, 250]
+            ]
+        }
+    },
+    bids: [{
+        bidder: 'adtrgtme',
+        params: {
+            sid: 1220291391,
+            bidOverride :{
+                imp: {
+                    bidfloor: 5.00 // bidOverride bidfloor
+                }
+            }
+            }
+        }
+    }]
+}];
