+    """ROOT I/O in pure Python and NumPy.
+
+    Uproot is a reader and a writer of the ROOT file format using only Python
+    and Numpy. Unlike the standard C++ ROOT implementation, Uproot is only an
+    I/O library, primarily intended to stream data into machine learning
+    libraries in Python. Unlike PyROOT and root_numpy, Uproot does not depend
+    on C++ ROOT. Instead, it uses Numpy to cast blocks of data from the ROOT
+    file as Numpy arrays."""
