 /**
- * Provides a registry/factory for Table objects.
- *
- * This registry allows you to centralize the configuration for tables
- * their connections and other meta-data.
- *
- * ### Configuring instances
- *
- * You may need to configure your table objects, using TableRegistry you can
- * centralize configuration. Any configuration set before instances are created
- * will be used when creating instances. If you modify configuration after
- * an instance is made, the instances *will not* be updated.
- *
- * ```
- * TableRegistry::config('Users', ['table' => 'my_users']);
- * ```
- *
- * Configuration data is stored *per alias* if you use the same table with
- * multiple aliases you will need to set configuration multiple times.
- *
- * ### Getting instances
- *
- * You can fetch instances out of the registry using get(). One instance is stored
- * per alias. Once an alias is populated the same instance will always be returned.
- * This is used to make the ORM use less memory and help make cyclic references easier
- * to solve.
- *
- * ```
- * $table = TableRegistry::get('Users', $config);
- * ```
- *
+ * Provides a default registry/factory for Table objects.
