+# 🤖 Artemis Session Container
+
+Dedicated, session-isolated container image for running the Artemis Autonomous AI Agent on Google Cloud **Container-Optimized OS (COS)**.
+
+---
+
+## 📌 Architecture & Lifecycle
+
+When a user initiates a session via the [Backend Manager](../backend_manager/README.md), the backend dynamically spawns an instance of this container named `artemis-session-<session_id>` on the shared `artemis-net` bridge network.
+
+---
+
+## 🔑 Key Features
+
+1. **Automated ADB Bridging**:
+   - The container entrypoint automatically connects to the target Cuttlefish instance with automatic retry handling.
+
+2. **Multimodal Perception & Toolchain**:
+   - Packaged with Android Platform Tools, ffmpeg, OpenCV libraries, and Python.
+
+3. **Real-time Event Streaming**:
+   - Hosts the Artemis Admin Console server exposing SSE and WebSocket endpoints for live streaming agent reasoning, thought steps, and action execution directly to the frontend.
+
+4. **Dynamic Selector & Coordinate Fallback Engine**:
+   - Drives real-time automated navigation on the connected Cuttlefish emulator using Artemis's multimodal reasoning pipeline.
+

+
+## 🚀 Building & Running
+
+### 1. Build the Artemis Container Image
+From the repository root:
+```bash
+docker build -f playground/artemis_container/Dockerfile -t artemis:latest .
+```
+
+### 2. Run Standalone with Docker CLI
+```bash
+# Ensure bridge network exists
+docker network create artemis-net || true
+
+# Run Artemis session container targeting Cuttlefish on port 6520
+docker run -d \
+  --name artemis-session-sample \
+  --network artemis-net \
+  --add-host host.docker.internal:host-gateway \
+  -e SESSION_ID=sample-123 \
+  -e ADB_DEVICE_SERIAL=host.docker.internal:6520 \
+  -e GEMINI_API_KEY="your-gemini-key" \
+  -p 8080:8080 \
+  artemis:latest
+```
+
+### 3. Run with Docker Compose (Test Setup)
+```bash
+cd playground/artemis_container
+docker-compose up -d
+```
+
+---
+
+## 🧪 Verification & Health Check
+
+1. **Verify ADB Connection inside Container**:
+   ```bash
+   docker exec -it artemis-session-sample adb devices
+   ```
+
+2. **Verify Server Health Probe**:
+   ```bash
+   curl http://localhost:8080/api/system/health
+   # Returns: {"status": "ok", ...}
+   ```
+
+3. **Verify Trace Streaming**:
+   ```bash
+   curl -N http://localhost:8080/stream/events
+   # Real-time Server-Sent Events stream
+   ```
