 # Introduction
 
-This chapter introduces you to the Opentrons Flex ecosystem, including the overall system design and available workstation configurations. It also includes important compliance and safety information, which you should review before setting up your Opentrons Flex robot. For more details on the features of Opentrons Flex, see the [System Description chapter](system-description.md).

-## Welcome to Opentrons Flex
-
 Opentrons Flex is a liquid-handling robot designed for high throughput and complex workflows. The Flex robot is the base of a modular system that includes pipettes, a labware gripper, deck fixtures, on-deck modules, and labware — all of which you can swap out yourself. Flex is designed with a touchscreen so you can work with it directly at the lab bench, or you can control it from across your lab with the Opentrons App or our open-source APIs.
 
 Flex workstations come with all of the equipment — robot, hardware, and labware — that you need to get started automating common lab tasks. For other applications, Opentrons Flex runs on fully open-source software and firmware, and is reagent- and labware-agnostic, giving you control over how you design and run your protocols.

 Opentrons Flex is part of the Opentrons liquid handler series of robots. Users of Opentrons Flex may be familiar with the Opentrons OT-2, our personal pipetting robot. Flex goes beyond the capabilities of OT-2 in several key areas, delivering higher throughput and walkaway time.

 Both Flex and OT-2 robots run on our open-source software, and the Opentrons App can control both types of robots at once. While OT-2 protocols can't be run directly on Flex, it's straightforward to adapt them (see the [OT-2 Protocols section][ot-2-python-protocols] of the Protocol Development chapter for details).
