+## Introduction ##
+
+Lean Engine is an open-source algorithmic trading engine built for easy strategy research, backtesting and live trading. We integrate with common data providers and brokerages so you can quickly deploy algorithmic trading strategies.
+
+The ToolBox project is a command line program which wraps over 15 tools.
+
+## Usage
