+    File Recorder, inherited from the built-in ``list``.
+
+    This recorder is used to record files generated by functional modules.
+    In principle, a CSST pipeline module should return a status (CsstStatus)
+    and a file recorder (``FileRecorder``) after it finishes data processing.
+
+    Methods
+    -------
+    add_record(filepath: str = "", db: bool = False, comment: str = "")
+        Add a file record, each record is a ``collections.namedtuple``.
+        Users should provide a file path ``filepath``, whether this file should be
+        written to database ``db``, a comment ``comment``.
+        An existence boolean will be attached to check if the file exists.
+    to_table()
+        Convert to ``astropy.table.Table``.
+    pprint(*args, **kwargs)
+        Use ``astropy.table.Table.pprint`` to print file records in table format.
+    pprint_all(*args, **kwargs)
+        Use ``astropy.table.Table.pprint_all`` to print file records in table format.
+
+    Examples
+    --------
+    >>> fr = FileRecorder()
+    >>> for i in range(3):
+    >>>     fr.add_record("test{:03d}.txt".format(i), db=True, comment="Test file {:d}".format(i))
