+
+### Code 11 Example
+
+```js
+symbology
+  .createStream({
+    symbology: symbology.Barcode.CODE128
+  }, '8765432164')
+  .then((data) => {
+    console.log('Result: ', data)
+  })
+```
+
+This will log:
+
+```json
+{
+  "data": "data:image/png+data;base64,PHN [...] eFd==`
+  "message": "",
+  "code": 0
+}
+```

+### MaxiCode Example
 
 ```js
-const symbology = require('symbology')
+symbology
+  .createFile({
+    symbology: Symbology.Barcode.MAXICODE,
+    option1: 2,
+    primary: '999999999840012',
+    fileName: 'maxiCodeExample.svg'
+  }, 'Secondary Message Here')
+  .then((data) => {
+    console.log('Result: ', data)
+  })
+```
+
+This creates `maxiCodeExample.svg` which looks like:
 
-(async function () {
-  try {
-    await data = symbology.createStream({
-      symbology: symbology.Barcode.CODE128,
-      backgroundColor: 'ff00ff',
-      foregroundColor: '00ff00'
-    }, '12345')

+  }, '01234567094987654321-01234')
+  .then((data) => {
     console.log('Result: ', data)
-  } catch (err) {
-    console.error('Error: ', err)
-  }
