-<p>Defining types using arrays may be error-prone, but <strong>graphql-php</strong> provides config validation
-tool to report when config has unexpected structure. </p>
-<p>This validation tool is <strong>disabled by default</strong> because it is time-consuming operation which only 
-makes sense during development.</p>
-<p>To enable validation - call: <code>GraphQL\Type\Definition\Config::enableValidation();</code> in your bootstrap
-but make sure to restrict it to debug/development mode only.</p>
-<h1 id="type-registry">Type Registry</h1>
-<p><strong>graphql-php</strong> expects that each type in Schema is presented with single instance. Therefore
-if you define your types as separate PHP classes you need to ensure that each type is referenced only once.</p>
-<p>Technically you can create several instances of your type (for example for tests), but <code>GraphQL\Schema</code> 
-will throw on attempt to add different instances with the same name.</p>
-<p>There are several ways to achieve this depending on your preferences. We provide reference 
-implementation below that introduces TypeRegistry class:</p>
