 **Angular Model** is a module that provides a simple way to bind client-side domain logic to JSON-based API resources.
 
 By sticking to hypermedia design principles, Angular Model allows you to implement client applications that are cleanly decoupled from your server architecture.
+
+## Basic Usage
+
+In your AngularJS application, include the JavaScript:
+
+```html
+// your specific paths may vary
+<script src="node_modules/radify/angular-model.js"></script>
+```
+
+In your app configuration, state a dependency on [Angular Model](https://github.com/radify/angular-model):
+
+```javascript
+angular.module('myApp', [
+	'ur.model'
+]);
+```
+
+## API documentation
+
+The source code is documented using the ngdoc standard using [gulp-ngdocs](https://www.npmjs.com/package/gulp-ngdocs/). A markdown version is browseable at [/docs](/docs/api.md).
+  
+To generate documentation in HTML, run:
+
+```bash
+gulp ngdocs
+```
+
+This will output docs into the `build/docs` directory. Then, using a server like `ws`, start a local web server:
+
+```bash
+cd build/docs
+npm install -g ws
+ws
+```
+
+Then, you should be able to browse to http://localhost:8000 to view the API documentation for angular-model.
+
+## Configuration
+
+Here is a quick reference guide to all the configuration settings you can pass to the model() constructor, which is [documented in full in the API documentation](/docs/api.md). Each one is then described in detail later in this document, and in full in the source code in the `src` directory.
+
+Setting | Type | Description
+------- | ---- | -----------
+url     | string | API url that this model maps to
+defaults | object literal | Default values of attributes of instances of this model. Similar to properties in OOP.
+$instance | object literal | Instance methods available on each instance of this model.
+$class | object literal | Class methods available on this model. Similar to static methods in OOP.
+$collection | object literal | Collection
+
+### Defaults
+
+```javascript
+yourApp.config(function(modelProvider) {
+    modelProvider.model('posts', {
+        /**
+         * @ngdoc object
+         * @name yourApp.posts.defaults
+         * @description
+         * Configure the default attributes for instances of posts.
+         *
+         * This is similar to an OOP class, which has attributes with defaults, e.g. "public string foo = 'bar';"
+         */
+        defaults: {
+            name: '',         // The name of the post
+            published: false, // Whether the post has been released to the general public
+            body: '',         // Body text of this post
+            logo: null,       // The logo to show for this post
+            author: 'John Doe'// Who wrote the post?
+        }
+    });
+});
+```
+
+Here is an example of how the defaults get used:
+
+```javascript
+var post = model('posts').create({});
+console.log(post.author);
+=> John Doe
+```
+
+## Creating instances of your model
+
+You can use angular-model ad-hoc to construct object instances:
+
+```javascript
+// From defaults
+var post = model('posts').create({});
+
+// Specifying fields
+var post = model('posts').create({
+  name: 'some post',
+  body: "body of some body, it's just some body, you know?",
+  author: 'Steve Davis'
+});
+
+console.log(post.author);
+=> Steve Davis
+```
+
+## Instance Methods
+
+angular-model instances have instance methods, similar to objects in the OOP world.
+
+### Default instance methods
+
+The following methods are available to every angular-model instance.
+
+Function | Description
+------- | -----------
+$save | Persist an instance to the API
+$delete | Tell the API to delete an instance
+$reload | Refresh an instance of a model from the API
+$revert | Reset the model to the state it was originally in when you first got it from the API
+$exists | Reset the model to the state it was originally in when you first got it from the API
+$dirty | Returns boolean - true if a model instance has been modified, else false. Opposite of $pristine.
+$pristine | Returns boolean - true if a model instance has unmodified, else false. Opposite of $pristine.
+$related | Hydrates the $links property of the instance. $links are used so that an instance can tell the client which objects are related to it. For example, a `post` may have an `author` object related to it.
+$modified | Returns a map of the properties that have been changed
+$hasRelated | Does an instance have a relation of name `name`?
+
+> You can see full details of these methods in the [API documentation](/docs/api.md).
+
+### Custom instance methods
+
+angular-model allows you to define instance methods on instances. This is similar to adding methods by extending a base class in the OOP world.
+
+```javascript
+yourApp.config(function(modelProvider) {
+    modelProvider.model('posts', {
+        // ...
+
+        /**
+         * @ngdoc object
+         * @name yourApp.posts.$instance
+         * @description
+         * Instance methods that are callable on any individual instance of a post
+         */
+        $instance: {
+            /**
+             * @ngdoc function
+             * @name yourApp.posts.$logo
+             * @description
+             * If this post instance has a logo, return it, otherwise return a default string
+             *
+             * @return string Either the logo for this post, or a default logo
+             */
+            $logo: function() {
+                var hasLogo = !!this.logo;
+                return hasLogo ? this.logo : '/logos/default.png';
+            }
+        }
+    });
+});
+```
+
+Example:
+
+```javascript
+var post = model('Posts').create({
+  logo: 'foo.png'
+});
+console.log(post.$logo());
+=> foo.png
+```
+
+## Class methods
+
+### Default class methods
+
+The following methods are available statically to angular-model:
+
+Function | Description
+-------- | -----------
+all | Make a request to the API, based on the `url` configuration setting
+first | Given a query, get the first model instance from the API
+create | Create a new instance of the model. Defaults come from the `defaults` configuration setting.
+
+> You can see full details of these methods in the [API documentation](/docs/api.md).
+
+### Custom class methods
+
+angular-model allows you to define class methods on instances. This is similar to static methods in the OOP world.
+
+```javascript
+yourApp.config(function(modelProvider) {
+    modelProvider.model('posts', {
+        // ...
+
+        /**
+         * @ngdoc object
+         * @name yourApp.posts.$class
+         * @description
+         * Class methods that are callable on the posts class, or any instance thereof. These
+         * behave similarly to static methods in OOP languages.
+         */
+        $class: {
+            /**
+             * @ngdoc function
+             * @name yourApp.posts.roles
+             * @description
+             * Get an array of valid post types.
+             *
+             * @return array The valid types that a post can have. Array of strings
+             */
+            types: function() {
+                return ['announcement', 'article']
+            }
+        }
+    });
+});
+```
+
+Example:
+
+```javascript
+console.log(model('Posts').types());
+=> ['announcement', 'article']
+```
+
+## Collection methods
+
+You can use collection methods as well, so you can deal with a bunch of instances together. This allows you to have powerful and expressive methods on collections.
+
+### Default collection methods
+
+The following methods are available statically to angular-model:
+
+Function | Description
+-------- | -----------
+add | Saves the `object` with `data`
+remove | Find `index` and delete it from the API, then remove it from the collection
+
+> You can see full details of these methods in the [API documentation](/docs/api.md).
+
+### Custom collection methods
+
+```javascript
+yourApp.config(function(modelProvider) {
+    modelProvider.model('posts', {
+        // ...
+
+        /**
+         * @ngdoc object
+         * @name yourApp.posts.$collection
+         * @description
+         * Methods that apply to a collection of posts together
+         */
+        $collection: {
+            /**
+             * @ngdoc function
+             * @name yourApp.posts.$hasArchived
+             * @description
+             * Operates on a collection of posts and determines whether any of them are archived
+             *
+             * @requires _ Lodash library is used to search the collection
+             *
+             * @return string Either the logo for this post, or a default logo
+             */
+            $hasArchived: function() {
+                return !angular.isUndefined(_.find(this, { archived: true }));
+            }
+        }
+    });
+});
+```
+
+Running unit tests
+--
+
+Install the test runner with npm:
+
+```bash
+npm install
+```
+
+You can then run the tests with Grunt:
+
+```bash
+grunt
+```
+
+Tests can be found in the `spec` directory of this project.
