 ## About
 
-The ROOT system provides a set of modules with all the functionality
-needed to handle and analyze large amounts of data in a very efficient way.
-Having the data defined as a set of objects, specialized storage methods are
-used to get direct access to the separate attributes of the selected objects,
-without having to touch the bulk of the data. Included are histograming
-methods in an arbitrary number of dimensions, curve fitting, function
-evaluation, minimization, graphics and visualization classes to allow
-the easy setup of an analysis system that can query and process the data
+ROOT is a unified software package for the storage, processing, and analysis of 
+scientific data: from its acquisition to the final visualization in form of highly 
+customizable, publication-ready plots. It is reliable, performant and well supported,
+easy to use and obtain, and strives to maximize the quantity and impact of scientific 
+results obtained per unit cost, both of human effort and computing resources.
+
+ROOT provides a very efficient storage system for data models, 
+that demonstrated to scale at the Large Hadron Collider experiments: Exabytes 
+of scientific data are written in columnar ROOT format.
+ROOT comes with histogramming capabilities in an arbitrary number of 
+dimensions, curve fitting, statistical modelling, minimization, to allow
+the easy setup of a data analysis system that can query and process the data
 interactively or in batch mode, as well as a general parallel processing
-framework, PROOF, that can considerably speed up an analysis.
+framework, RDataFrame, that can considerably speed up an analysis, taking 
+full advantage of multi-core and distributed systems.
 
-Thanks to the built-in C++ interpreter cling, the command, the
-scripting and the programming language are all C++. The interpreter
-allows for fast prototyping of the macros since it removes the time
-consuming compile/link cycle. It also provides a good environment to
-learn C++. If more performance is needed the interactively developed
-macros can be compiled using a C++ compiler via a machine independent
-transparent compiler interface called ACliC.
+ROOT is performance critical software written in C++ and enables rapid prototyping 
+powered by a unique C++ compliant interpreter called Cling. 
+Cling also enables performant C++ type introspection which is a building block of automatic 
+interoperability with Python. Thanks to PyROOT, leveraging the cppyy technology, 
+ROOT offers efficient, on-demand C++/Python interoperability in a uniform cross-language 
+execution environment.
 
-The system has been designed in such a way that it can query its databases
-in parallel on clusters of workstations or many-core machines. ROOT is
-an open system that can be dynamically extended by linking external
-libraries. This makes ROOT a premier platform on which to build data
-acquisition, simulation and data analysis systems.
+ROOT fully embraces open-source, it's made with passion by its community,
+for the benefit of its community.
