+
 Safe environments for agents. Built by Docker.
 
 [![GitHub Release](https://img.shields.io/github/v/release/docker/sbx-releases?color=2560ff&labelColor=e7eaef)](https://github.com/docker/sbx-releases/releases/latest)
 
 # What it does
+
 It provides sandboxes with controlled access to your filesystem, network, and tools. This means your agents can work autonomously without putting your machine or data at risk.
 
 # Details
+
 - Docker-native isolation. Same containerization principles trusted by 20M+ developers.
 - Vendor-neutral. Works with the models and tools you’re already using.
 
 # What you get
+
 - YOLO mode by default: agents work without asking permission
 - Private Docker daemon for running test containers
 - File access controls between host and sandbox
