+ChronoSync: synchronization library for distributed realtime applications for NDN
+=================================================================================
+
+In supporting many distributed applications, such as group text messaging, file sharing,
+and joint editing, a basic requirement is the efficient and robust synchronization of
+knowledge about the dataset such as text messages, changes to the shared folder, or
+document edits. This library implements
+[ChronoSync protocol](http://named-data.net/wp-content/uploads/2014/03/chronosync-icnp2013.pdf),
+which exploits the features of the Named Data Networking architecture to efficiently
+synchronize the state of a dataset among a distributed group of users. Using appropriate
+naming rules, ChronoSync summarizes the state of a dataset in a condensed cryptographic
+digest form and exchange it among the distributed parties. Differences of the dataset can
+be inferred from the digests and disseminated efficiently to all parties. With the
+complete and up-to-date knowledge of the dataset changes, applications can decide whether
+or when to fetch which pieces of the data.
+
+ChronoSync uses [ndn-cxx](https://github.com/named-data/ndn-cxx) library as NDN
+ development library.
+
+ChronoSync is an open source project licensed under GPL 3.0 (see `COPYING.md` for more
+detail). We highly welcome all contributions to the ChronoSync code base, provided that
+they can licensed under GPL 3.0+ or other compatible license.

+
+Installation instructions
+-------------------------
+
+### Prerequisites
+
+Required:
+
+* [ndn-cxx and its dependencies](http://named-data.net/doc/ndn-cxx/)
+* Boost libraries
+* `protobuf` library
+* log4cxx (optional, if enabled with `--with-log4cxx` configure option)
+
+### Build
+
+To build ChronoSync from the source:
+
+ ./waf configure
+ ./waf
+ sudo ./waf install
+
+If configured with tests: `./waf configure --with-tests`), the above commands will also
+generate unit tests in `./build/unit-tests`
