+### Simple Static Floors
+
+Some publishers just want to set a simple static floor. Please don't use this module for that. This module should only be used when you need to vary the floor by mediatype, size, etc. Here's how you can set static floors on each Prebid adunit:
+
+```javascript
+pbjs.addAdUnits({
+    code: "test-div",
+    mediaTypes: {
+        banner: {
+            sizes: [[300,250]]
+        }
+    },
+    ortb2Imp: {
+        bidfloor: 1.00,
+        bidfloorcur: "EUR"
+    },
+    // ...
+});
+```
+
 ## How it Works
 
 There are several places where the Floor module changes the behavior of the Prebid.js auction process. Below is a diagram describing the general flow of the client-side Price Floors Module:

 ### Defining Floor data

 As described in the [Signaling](#floor-signaling) section above, floor data may be defined in several ways. Here's the order of priority:
 
 1. Dynamic data - if PBS finds recent (non-expired) floors data from a dynamic floors vendor, that takes precedence.
