 pyControl makes it easy to program complex behavioural tasks using a clean, intuitive, and flexible syntax for specifying tasks as state machines. User created task definition files, written in Python, run directly on the microcontroller, supported by pyControl framework code.  This gives users the power and simplicity of Python for specifying task behaviour, while allowing advanced users low-level access to the microcontroller hardware.  For more information see [programming tasks](user-guide/programming-tasks.md).
 
-pyControl [hardware](user-guide/hardware.md) consists of a breakout board that interfaces the microcontroller with a set of connectors, and a family of devices such as nose pokes, audio boards, LED drivers, rotary encoders and stepper motor controllers that can be used to create a wide variety of different behavioural setups.

 pyControl has a [Graphical User Interface](user-guide/graphical-user-interface.md) (GUI) and a [Command Line Interface](user-guide/command-line-interface.md) (CLI).   The GUI is the recommended way to get started with pyControl.  The command line interface provides tools for running tasks on many setups in parallel.

 ## Overview
 
-A typical pyControl hardware setup consists of one or more breakout boards connected to a computer by USB, each of which runs a single behavioural setup.  The breakout board connects to a set of devices such as nosepokes, audio boards and LED drivers which make up the setup.

USB hubs can be used between the computer and breakout boards such that many setups can be controlled from a single computer.
 
-All pyControl hardware is open source and design files for the hardware detailed below are available in the [pyControl hardware repository](https://bitbucket.org/takam/pycontrol_hardware).  The repository also has a list of [useful parts](https://bitbucket.org/takam/pycontrol_hardware/src/default/useful-parts-list.md) such as cables, solenoids, mounting hardware etc for building pyControl setups.
