+The km3io Python package
+========================
+
+This software provides a set of Python classes to read KM3NeT ROOT files
+without having ROOT, Jpp or aanet installed. It only depends on Python 3.5+ and
+the amazing uproot package and gives you access to the data via numpy arrays.
+
+It's very easy to use and according to the uproot benchmarks, it is able to
+outperform the ROOT I/O performance. To install it::
+
+    pip install km3io
+
+Quick intro to read Jpp files
+-----------------------------
+
+Currently only events (the ``KM3NET_EVENT`` tree) are supported but timeslices
+and summaryslices will be implemented very soon.
+
+Let's have a look at some ORCA data (``KM3NeT_00000044_00005404.root``)
+
+To get a lazy ragged array of the events::
+
+    >>> import km3io as ki
+    >>> events = ki.JppReader("KM3NeT_00000044_00005404.root").events
+
+That's it! Now let's have a look at the hits data::
+
+    >>> events
+    Number of events: 17023
+    >>> events[23].snapshot_hits.tot
+    array([28, 22, 17, 29,  5, 27, 24, 26, 21, 28, 26, 21, 26, 24, 17, 28, 23,
+           29, 27, 24, 23, 26, 29, 25, 18, 28, 24, 28, 26, 20, 25, 31, 28, 23,
+           26, 21, 30, 33, 27, 16, 23, 24, 19, 24, 27, 22, 23, 21, 25, 16, 28,
+           22, 22, 29, 24, 29, 24, 24, 25, 25, 21, 31, 26, 28, 30, 42, 28],
+          dtype=uint8)
