+# Description
+RNTuple is the next-generation data format for high-energy physics (HEP) data collected from the LHC.
+It is part of ROOT, a cornerstone software package for the storage, visualization and analysis of scientific data, widely used in the scientific community and particularly in HEP.
+ROOT is a C++ and Python framework, but it recently became available in the browsers as well through a Javascript implementation of some of its parts: *JSROOT*.
+Since RNTuple is still in the experimental phase, it currently lacks a JSROOT interface and its contents cannot be visualized in the browser, a common and desirable property of many ROOT objects.
+The goal of this project is filling this gap by making JSROOT able to read and display data stored inside an RNTuple.
+
+## Task ideas
+In this project, the student will learn the internals of the RNTuple binary format and use this knowledge to implement a Javascript interface to expose RNTuple to JSROOT.
+
+## Expected results and milestones
+ * Familiarize with the JSROOT framework, understanding how to integrate new components into it;
+ * read and implement (a subset of) the RNTuple [binary format specifications](https://github.com/root-project/root/blob/master/tree/ntuple/v7/doc/BinaryFormatSpecification.md), in Javascript; this will concretely mean implementing the deserialization code from a binary blob to a RNTuple object that may be used by JSROOT;
+ * enable the visualization of an RNTuple's fields in the browser, leveraging the existing framework in JSROOT.
+
+## Requirements
+  * Knowledge of Javascript / ES6
+  * Basic knowledge of "low-level" programming (primitive types binary layouts, bit-level manipulations, reinterpreting bytes as different types, ...)
+  * Experience with git / github
+  * (Bonus): familiarity with any binary format
