 # Monero C++ Library
 
-This project is a lightweight wrapper of [Monero Core's](https://github.com/monero-project/monero) C++ wallet, [wallet2](https://github.com/monero-project/monero/blob/master/src/wallet/wallet2.h), which conforms to the specification defined [here](https://github.com/monero-ecosystem/monero-javascript/blob/master/monero-model.pdf).
+This project is a library for working with Monero wallets in C++ by wrapping [Monero Core's](https://github.com/monero-project/monero) C++ wallet, [wallet2](https://github.com/monero-project/monero/blob/master/src/wallet/wallet2.h).
 
-The purpose of this library is to define common daemon and wallet types for a general-purpose Monero API which focuses on ease-of-use.  
+In addition, this project conforms to an [API specification](https://github.com/monero-ecosystem/monero-java/blob/master/monero-spec.pdf) intended to be intuitive, robust, and for long-term use in the Monero project.
 
-This library may be used to build Monero-related GUI applications, libraries in other languages (e.g. [monero-java](https://github.com/monero-ecosystem/monero-java-rpc)), or a conformant REST/JSON-RPC API.

+## Main Features
+
+- Manage a Monero wallet
+- Object-oriented model with rigorous focus on ease-of-use
+- Query wallet transactions, transfers, and outputs by their many attributes
+- Receive notifications as a wallet is synchronized, when blocks are added to the chain, or when the wallet sends or receives transfers
