 BROS2 (Block ROS2) is an Electron desktop environment for building, simulating, and introspecting ROS2 graphs with a drag-and-drop block interface. It streamlines going from idea to runnable robot behavior by generating ROS packages, launch files, and providing live insight into running nodes.
 
 Basically, BROS2 (Block ROS2) is an Electron desktop app that lets you assemble ROS2 graphs visually and run them through a managed Docker workspace 🦾🤖
 
-## Why BROS2?
+## 🔎 Why BROS2?
 - Visual composition of ROS 2 nodes, topics, and services without leaving the editor.
 - Automatic generation of package scaffolding and launch files from the block graph.
 - Integrated simulation hooks (Gazebo, Isaac) and telemetry panels for rapid iteration.
 - Cross-platform desktop app distributed via Electron so teams share a single workflow.
 
-## Requirements
+## 📋 Requirements
 - macOS (Apple Silicon or Intel) or Linux with Docker Desktop / Docker Engine running.
 - Git, curl, and bash (used by the bootstrap script).
 - Internet access to download Node, pnpm, and Electron during setup.

-## Tips
+## 💡 Tips
 - Keep Docker running whenever you use `window.runner.*`; the runner manages containers in `Projects/`.
 - If `pnpm dev` fails because Electron is missing, re-run `node node_modules/electron/install.js`.
 - Rerun the bootstrap script after major Node/pnpm upgrades—it is idempotent and safe to run again.
