+```
+
+Terminal 2:
+```bash
+npm run dev            # Frontend on :5173
+```

+# DimSim
+
+3D simulation environment for the [dimos](https://github.com/dimensionalOS/dimos) robotics stack.
+
+Browser-based Three.js + Rapier simulator with LCM transport, sensor publishing (RGB, depth, LiDAR, odometry), and an eval harness for automated testing of navigation and perception pipelines.
+
+## Install
+
+```sh
+deno install -gAf --unstable-net jsr:@antim/dimsim
+```
+
+## Setup
+
+Download core assets (~22 MB) and install a scene:
+
+```sh
+dimsim setup
+dimsim scene install apt
+```
+
+## Run
+
+Start the dev server and open the URL it prints:
+
+```sh
+dimsim dev --scene apt
+```
+
+Run headless evals in CI:
+
+```sh
+dimsim eval --headless --env apt --workflow reach-vase
+```
+
+## Programmatic API
+
+```ts
+import { startBridgeServer } from "@antim/dimsim";
+
+startBridgeServer({ port: 8090, distDir: "./dist", scene: "apt" });
+```
+
+## Commands
+
+| Command | Description |
+|---------|-------------|
+| `dimsim setup` | Download core assets |
+| `dimsim scene install <name>` | Install a scene |
+| `dimsim scene list` | List available and installed scenes |
+| `dimsim scene remove <name>` | Remove a scene |
+| `dimsim dev [--scene <name>]` | Dev server (open browser manually) |
+| `dimsim eval --headless` | Run eval workflows in CI |
+| `dimsim agent` | Launch dimos Python agent |
