+
+    Parameters
+    ----------
+    filename
+        A string defining the target filename path.
+    file
+        A file-like object using "rb" mode --> open(filename, "rb").
+    metadata_last_modified
+        The last modified date for the document.
+    languages
+        User defined value for `metadata.languages` if provided. Otherwise language is detected
+        using naive Bayesian filter via `langdetect`. Multiple languages indicates text could be
+        in either language.
+        Additional Parameters:
+            detect_language_per_element
+                Detect language per element instead of at the document level.
