+#### Adding arguments
+
+You can add arguments to basic crud operations, but keep in mind you'll need to use your own
+resolver, as the default resolvers will not be aware of any custom arguments you've allowed.

+Using YAML, simply use a map of options instead of `true`.

+#### Adding related objects
+
+The `Post` type we're using has a `$has_one` relation to `Author` (Member), and plural relationships
+to `File` and `Comment`. Let's expose both of those to the query.
+
+For the `$has_one`, the relationship can simply be declared as a field. For `$has_many`, `$many_many`,
+and any custom getter that returns a `DataList`, we can set up a nested query.

-Relations are treated just like fields, and the new types are automatically detected, and added to the schema. By 
-default, these new types offer only `ID` as an exposed field (a configuration setting), so we'll probably want to 
-customise that a bit. 
+Notice that we can only query the `ID` field of `Files` and `Author`, our new related fields.
+This is because the types are implicitly created by the configuration, but only to the point that
+they exist in the schema. They won't eagerly add fields. That's still up to you. By default, you'll only
+get the `ID` field, as configured in `SilverStripe\GraphQL\Scaffolding\Scaffolders\DataObjectScaffolder.default_fields`.
+
+Let's add some more fields.

-None of these new types have queries or mutations associated with them, but we can now access them as data related to 
-our `Post` object.
 
-Notice that we're able to use the computated value 'Name', which resolves to 'getName()' on the Member object. 
-Fields are not necessarily one-to-one with `$db`. They are simply any public method on the DataObject that returns a 
-`DataList`, `DataObject`, or `DBField`.

-### Ready-made CRUD operations
 
-Even with the fluency of scaffolding, many of these operations may look the same, and the resolver functions may start 
-to get repetitive with each simple read, create, edit, delete operation we offer. For basic CRUD definitions, you can 
-use the operations that come bundled with the scaffolder and save a lot configuration effort.
+#### Whitelisting fields in bulk
 
-These ready-made operations will automatically generate input types and add them to your schema. They offer very basic 
-functionality that checks for permission and performs a simple CRUD operation on your DataObject.
+If you have a type you want to be fairly well exposed, it can be tedious to add each
+field piecemeal. As a shortcut, you can use `addAllFieldsExcept()` (code) or `fieldsExcept` (yaml).
 
+**Via YAML**:
+```yaml
+SilverStripe\GraphQL:
+  schema:
+    scaffolding:
+      types:
+        MyProject\GraphQL\Post:
+          fieldsExcept: [SecretThing]
+```
 
-**Code:**
+**... Or with code**:
 ```php
-	$scaffolder->dataObject(Post::class)
-		->addFields(['ID','Title','Content','Author','Files'])
-		->query(GraphQLScaffolder::READ)
-		->mutation(GraphQLScaffolder::UPDATE)
-		->mutation(GraphQLScaffolder::DELETE)
-		->mutation(GraphQLScaffolder::CREATE)
+	$scaffolder
+		->type(Post::class)
+			->addAllFieldsExcept(['SecretThing'])
 ```
 
-For YAML, the API is slightly different. You'll need the `operations` setting for this.
+#### Adding arbitrary queries and mutations
 
-**YAML**:
+Not every operation maps to simple CRUD. For this, you can define custom queries and mutations
+in your schema, so long as they map to an existing type.

+          paginate: false
+          resolver: MyProject\GraphQL\LatestPostResolver
 ```
 
-> As shorthand, the expression `[CREATE, READ, UPDATE, DELETE]` can also be expressed as `operations: all`.
+**... Or with code**:
+```php
+	$scaffolder
+		->type(Post::class)
+			//...            
+        ->mutation('updatePostTitle', Post::class)
+            ->addArgs([
+                'ID' => 'ID!',
+                'NewTitle' => 'String!'
+            ])
+            ->setResolver(function($obj, $args) {
+                $post = Post::get()->byID($args['ID']);
+                if($post->canEdit()) {
+                    $post->Title = $args['NewTitle'];
+                    $post->write();
+                }
 
-We now have a new queries and mutations with automatically generated names:
+                return $post;
+            })
+            ->end()
+	    ->query('latestPost', Post::class)
+        	->setUsePagination(false)
+        	->setResolver(function($obj, $args) {
+        		return Post::get()->sort('Date', 'DESC')->first();
+        	})
+        	->end()
+```
+
+**GraphQL**
+```
+mutation updatePostTitle(ID: 123, NewTitle: 'Foo') {
+	Title
+}
+```
+
+```
+query latestPost {
+	Title
+}
+```
+
+#### Dealing with inheritence
+
+Adding any given type will implicitly add all of its ancestors, all the way back to `DataObject`.
+Any fields you've listed on a descendant that are available on those ancestors will be exposed on the ancestors
+as well. For CRUD operations, each ancestor gets its own set of operations and input types.
+
+**Via YAML**:
+```yaml
+SilverStripe\GraphQL:
+  schema:
+    scaffolding:
+      types:
+        MyProject\GraphQL\Post:
+          ##...
+        SilverStripe\CMS\Model\RedirectorPage:
+          fields: [ExternalURL, Content]
+          operations:
+            read: true
+            create: true
+        Page:
+          fields: [MyCustomField]
+```
+
+**... Or with code**:
+```php
+	$scaffolder
+        ->type('SilverStripe\CMS\Model\RedirectorPage')
+        	->addFields(['ExternalURL','Content'])
+        	->operation(GraphQLScaffolder::READ)
+        		->end()
+        	->operation(GraphQLScaffolder::CREATE)
+        		->end()
+        	->end()
+        ->type('Page')
+        	->addFields(['MyCustomField'])
+        	->end();
+```
+
+We now have the following added to our schema:
+
+```
+type RedirectorPage {
+	ID
+	ExternalURL
+	Content
+	MyCustomField
+}
+
+type Page {
+	ID
+	Content
+	MyCustomField
+}
+
+type SiteTree {
+	ID
+	Content
+}
+
+query readRedirectorPages {
+	RedirectorPage
+}
+
+query readPages {
+	Page
+}
+
+query readSiteTrees {
+	SiteTree
+}
+
+mutation createRedirectorPage {
+	RedirectorPageCreateInputType
+}
+
+mutation createPage {
+	PageCreateInputType
+}
+
+mutation createSiteTree {
+	SiteTreeCreateInputType
+}
+```
 
-* readPosts
-* createPost(Input: PostCreateInputType)
-* updatePost(ID: ID!, Input: PostUpdateInputType)
-* deletePost(ID: ID!)
