 ## Hardware
 
-First things first: you need a robot. And not just a robot you need a way to control it, a way to see what it's doing, and a way to record demonstrations. Luckily, that's where LeRobot comes in. In this section we walk through every piece of hardware we used. Some of these choices were obvious in advance. Others like the wrist strap and small details turned out to be surprisingly important.
+LeRobot takes care of the entire robot learning stack: in this section we're gonna walk you through every piece of hardware we used. 
 
 ### The Robot: Bimanual Open Arms
 
-We use the **bimanual [Open Arms](https://huggingface.co/docs/lerobot/openarm)**, they are open-source, human-like robot arms developed by [Enetic](https://openarm.dev) and built by [WowRobot](https://shop.wowrobo.com). Three reasons drove this choice:
+For starters, we need a robot (duh). We use the **bimanual [Open Arms](https://huggingface.co/docs/lerobot/openarm)**, they are open-source, human-like robot arms developed by [Enetic](https://openarm.dev) and built by [WowRobot](https://shop.wowrobo.com). Three reasons drove this choice:
 
 1. **The humanoid trend.** We're seeing a wave of human-like robots. More human-form robots means more human-form data in the ecosystem. Building on this form factor positions our work for a future where human-like manipulation data is transferable.
 2. **Smaller teleop gap.** When the robot's kinematics match a human arm, the teleoperator's motions transfer more naturally less mental remapping, faster learning.

+Next, we need a way to actually control the robot. 
 
 We started with full-size Open Arms as leader arms for teleoperation. They seemed like the natural choice: same kinematics as the follower arms, one-to-one mapping.
