 To find all entries  of a content type, use the query given below:
 
-    $result = $stack->ContentType(CONTENT_TYPE_UID)->Query()->toJSON()->includeCount()->includeContentType()->find()
-    // $result[0] - array of entries
-    // $result[1] - content type

+// $result[0] - array of entries
+// $result[1] - content type
+// $result[2] - count of the entries
+```
 
 To fetch a specific entry from a content type, use the following query:
 
-    $result = $stack->ContentType(CONTENT_TYPE_UID)->Entry(ENTRY_UID)->toJSON()->fetch()
-    // $result - entry object
