 Setting the `cloud_name`, `api_key` and `api_secret` parameters can be done either directly in each call to a Cloudinary method, by calling the cloudinary.config(), or by using the CLOUDINARY_URL environment variable.

 ### Overriding the request agent
 To override the request agent pass the agent into any method that makes a
 request and it will be used instead of the normal https agent. e.g
-```js
 
+```js
 cloudinary.uploader.upload_stream(
-  function(result) { console.log(result); },
-  { agent: myAgent }
+  { agent: myAgent },
+  function(error, result) { console.log(result); }

 The following example generates the url for accessing an uploaded `sample` image while transforming it to fill a 100x150 rectangle:

 Another example, emedding a smaller version of an uploaded image while generating a 90x90 face detection based thumbnail:

 You can provide either a Facebook name or a numeric ID of a Facebook profile or a fan page.
 
 Embedding a Facebook profile to match your graphic design is very simple:

 The uploaded image is assigned a randomly generated public ID. The image is immediately available for download through a CDN:

 ### cloudinary.upload_stream
 
 You can use cloudinary.upload_stream to write to the uploader as a stream:
 
-    var fs = require('fs');
-    var stream = cloudinary.uploader.upload_stream(function(result) { console.log(result); });
-    var file_reader = fs.createReadStream('my_picture.jpg', {encoding: 'binary'}).on('data', stream.write).on('end', stream.end);
+```js
+var fs = require('fs');
+var stream = cloudinary.uploader.upload_stream(function(error, result) { console.log(result); });
+var file_reader = fs.createReadStream('my_picture.jpg', {encoding: 'binary'}).on('data', stream.write).on('end', stream.end);
+```
 
 #### Version 1.1 upload_stream change notes
 The `upload_stream` method was modified to return a `Transform` stream object, we advise to change the `on('data')` and `on('end')` to pipe API:
 
-    var file_reader = fs.createReadStream('my_picture.jpg').pipe(stream);
+```js
+var file_reader = fs.createReadStream('my_picture.jpg').pipe(stream);
 
+```
 if you still need to use event chanining, you can wrap `stream.write` and `stream.end` with wrapper functions
 
-    var file_reader = fs.createReadStream('my_picture.jpg', {encoding: 'binary'}).
-      on('data', function(data){stream.write(data)}).on('end', function(){stream.end()});
-
+```js
+var file_reader = fs.createReadStream('my_picture.jpg', {encoding: 'binary'})
+  .on('data', function(data){stream.write(data)})
+  .on('end', function(){stream.end()});
+```
 ### cloudinary.image
 
 Returns an html image tag pointing to Cloudinary.
 
 Usage:
 
-    cloudinary.image("sample", {format: "png", width: 100, height: 100, crop: "fill"})
+```js
+cloudinary.image("sample", {format: "png", width: 100, height: 100, crop: "fill"})
 
-    // <img src='http://res.cloudinary.com/demo/image/upload/c_fill,h_100,w_100/sample.png' height='100' width='100'/>
+// <img src='http://res.cloudinary.com/demo/image/upload/c_fill,h_100,w_100/sample.png' height='100' width='100'/>
