 Scorex and Scorex 2
 -------------------
 
-It is experimental and still raw new major release of the Scorex. Previous
-version with documentation could be found at [https://github.com/input-output-hk/Scorex](https://github.com/input-output-hk/Scorex).
+Scorex 2 is modular blockchain framework is Scala language which allows for free and limitless experimentation with a 
+wide variety of designs. 
 
+It is a complete rewrite of Scorex framework, which can be found 
+at [https://github.com/input-output-hk/Scorex](https://github.com/input-output-hk/Scorex).
 
 Motivation
 ----------
 
- Bitcoin Core source code contains more 100K lines of code(80K of C++ only), Nxt is more than 45K
- line of Java code. All parts of the design(network/transactional/consensus protocols) are mixed in a hard way.
- So researchers and developers are not in good start positions to make experiments.
+ If you have a new design for a blockchain system, there are few options available in regards with an implementation:
+ * you can fork codebase of a Bitcoin or Ethereum client. However, such clients are optimized towards concrete 
+ protocol, thus implementing something different would be a cumbersome task.
+ * there are some modular frameworks, such as Scorex, where you can change consensus layer, or transactional
+   layer, or both. Still, these modules have concrete interfaces, so for many design
+
+ We have read a lot of research papers to make Scorex 2 supporting their implementations. Its abstract core 
+ allows for implementing a broad range of systems, including ones with multiple types of blocks and non-linear history.
 
- In opposite, Scorex core is less than 4K lines of Scala code. Abstract core concepts allow to implement a broad range
- of systems, including ones with multiple types of blocks and non-linear history.
 
 Features
 --------
 
-* Compact, functional code
-* Modular design with fine granularity
-* Scala language
-* Asynchronous network layer on top of TCP
-* JSON API
-* Command line client for the JSON API
-* Cryptographic primitives externalized into [separate scrypto framework](https://github.com/input-output-hk/scrypto)
-* Few examples out-of-box

+There is tutorial in progress, available at [https://github.com/ScorexFoundation/ScorexTutorial](https://github.com/ScorexFoundation/ScorexTutorial).
 
 Examples
 --------
 
-There are two examples of blockchain systems built with Scorex. Details are available in 
-the [dedicated readme](examples/README.md).
+There are two examples of blockchain systems built with Scorex:
+ * implementation of TwinsCoin, a hybrid (Proof-of-Work + Proof-of-Stake) cryptocurrency is provided in this repository,
+  please check [dedicated readme](examples/README.md).
+ * [TreasuryCoin](https://github.com/input-output-hk/TreasuryCoin) is an experimental implementation of the perspective 
+ treasury system described in [A Treasury System for Cryptocurrencies: Enabling Better Collaborative Intelligence](https://eprint.iacr.org/2018/435.pdf). 
+ * [Ergo Platform](https://github.com/ergoplatform/ergo), a Proof-of-Work cryptocurrency and financial contracts 
+ platform, with support for stateless nodes, different operating regimes with up to 4 possible sections in a block etc.
 
+Development Plans
+-----------------
 
+Final 1.0 release of Scorex 2 is not done but near. Currently we're polishing and auditing the codebase towards the 
+release. Then we will consider further plans, possibly including:
+
+ * Improved networking layer
+ * Support for Scala 3
+ * More examples, possibly including non-linear systems (such as DAGs)
 
 Contributions
 -------------
 
 Contributions are welcome! Please take a look into [issues](https://github.com/ScorexFoundation/ScorexTutorial/issues).
- Testing codebase is very small at the moment, so writing a test is not just good for start, but useful for the product as well.
+ Testing codebase is still not perfect at the moment, so writing a test is not just good for start, 
+ but useful for the product as well.
+
+New examples would be very helpful as well!
