 ### Using .proto files
 
+It's super easy to load an existing .proto file using the full build, which parses and compiles the definitions to ready to use runtime message classes:

 package awesomepackage;

+### Using JSON descriptors
+
+The library utilizes a JSON format that is equivalent to a .proto definition (see also: [Command line usage](#command-line)). The following is identical to the .proto definition seen above:
+
+```json
+// awesome.json
+{
+  "nested": {
+    "AwesomeMessage": {
+      "fields": {
+        "awesomeField": {
+          "type": "string",
+          "id": 1
+        }
+      }
+    }
+  }
+}
+```
+
+A JSON descriptor can either be loaded the usual way:
+
+```js
+protobuf.load("awesome.json", function(err, root) {
+    if (err) throw err;
+
+    // Continue at "Obtain a message type" above
+});
+```
+
+Or you can load it inline:
+
+```js
+var root = protobuf.Root.fromJSON(descriptorJson);
+
+// Continue at "Obtain a message type" above
+```
+
+
 ### Using reflection only
 
+Both the full and the light build include full reflection support. You could, for example, define the .proto definitions seen in the example above using just reflection:

+Detailed information on the reflection structure is available within the [documentation](#documentation).
+
 ### Using custom classes
 
+You can also extend runtime message classes with your own custom functionality by registering your own class with a reflected message type:
+
 ```js
 ...
 
-// define your own prototypical class
+// Define your own prototypal class
 function AwesomeMessage(properties) {
     protobuf.Message.call(this, properties); // call the super constructor
 }
 
-// register your custom class with its reflected type
+// Register your custom class with its reflected type (*)
 protobuf.Class.create(root.lookup("awesomepackage.AwesomeMessage") /* or use reflection */, AwesomeMessage);
 
-// define your custom functionality
+// Define your custom functionality
 AwesomeMessage.customStaticMethod = function() { ... };
 AwesomeMessage.prototype.customInstanceMethod = function() { ... };
 
-// create a message
-var message = new AwesomeMessage({ awesomeField: "AwesomeString" });
-
-// Continue at "Encode a message" above
+// Continue at "Create a message" above (you can also use the constructor directly)
 ```
 
-Custom classes are automatically populated with static `encode`, `encodeDelimited`, `decode`, `decodeDelimited` and `verify` methods and reference their reflected type via the `$type` property. Note that there are no methods (just `$type`) on instances by default as method names might conflict with field names.
+(*) Besides referencing its reflected type through `AwesomeMessage.$type` and `AwesomeMesage#$type`, the respective custom class is automatically populated with:
 
-### Using the Reader/Writer interface directly
+* `AwesomeMessage.create`
+* `AwesomeMessage.encode` and `AwesomeMessage.encodeDelimited`
+* `AwesomeMessage.decode` and `AwesomeMessage.decodeDelimited`
+* `AwesomeMessage.verify`
+* `AwesomeMessage.fromObject`, `AwesomeMessage.toObject`, `AwesomeMessage#toObject` and `AwesomeMessage#toJSON`
 
-While only useful for the adventurous cherishing an aversion to [generated static code](https://github.com/dcodeIO/protobuf.js#command-line), it's also possible to use the Reader/Writer interface directly depending just on the [minimal library][dist-minimal] ([basic example](https://github.com/dcodeIO/protobuf.js/blob/master/examples/reader-writer.js)).
