 You can write your fixtures files manually and load them in to your applications. Below is a sample data.yml fixtures file. You can also split your data fixtures file up in to multiple files. Doctrine will read all fixtures files and parse them, then load all data.
 
-Please see the [doc schema-files :index :name] for the sample models/schema for these example fixtures.
+Imagine a schema with the following relationships:
+
+<code type="php">
+Resource hasMany Tag as Tags
+Resource hasOne ResourceType as Type
+ResourceType hasMany Resource as Resources
+Tag hasMany Resource as Resources
+</code>
