+### Context Example
+
+```javascript
+  var DataTransform = require("node-json-transform").DataTransform;
+```
+
+First we need some data.
+
+```javascript
+    var data = {
+        posts : [
+            {
+                title : "title1",
+                description: "description1"
+            }
+        ]
+    };
+```
+
+The map defines how the output will be structured and which operations to run.
+
+```javascript
+    var map = {
+        list : 'posts',
+        item: {
+            name: "title",
+            info: "description"
+        },
+        operate: [
+            {
+                run: function(val, context) { return val + " more info for" + context.type},
+                on: "info"
+            }
+        ],
+        each: function(item, index, collection, context){
+            // make changes
+            item.type = context.type;
+            return item;
+        }
+    };
+```
+
+Run it
+```javascript
+    var dataTransform = DataTransform(data, map);
+    var context = { type: 'my-type' };
+    var result = dataTransform.transform(context);
+    console.log(result);
+```
+
+The expected output.
+```javascript
+    [
+        {
+            name : "title1",
+            info: "description1 more info for my-type",
+            type: 'my-type'
+        }
+    ]
+```
+
+
 Enjoy!
