+
+## Docker Support
+
+This project is fully compatible with **Docker** and can be run as a container.  
+The provided Docker image exposes the service and allows you to configure runtime behavior via environment variables.
+
+### Run with `docker run`
+
+```bash
+docker run -d \
+  -p 30000:30000 \
+  -e GRPC_ENABLED=true \
+  -e GRPC_PASSPHRASE=my-secure-secret \
+  ghcr.io/OWNER/IMAGE_NAME:latest
+```
+
+### Run with Docker Compose
+
+```yaml
+services:
+  app:
+    image: ghcr.io/dev-claw/vripper-web:latest
+    environment:
+      - GRPC_ENABLED=true
+      - GRPC_PASSPHRASE=super-secret-passphrase
+    ports:
+      - "30000:30000"
+```
+
+> **Tip:** For production, prefer storing the passphrase as a secret (see `Security Notes` below) rather than writing it
+> directly in the Compose file.
+
+### Environment Variables
+
+The container supports these environment variables for enabling and securing the gRPC server.
+
+### `GRPC_ENABLED`
+
+- **Type:** String (interpreted as Boolean)
+- **Accepted values:** `true` (case-insensitive) to enable; any other value or unset → disabled
+- **Default:** `false` (gRPC disabled)
+- **Behavior:**
+    - When `GRPC_ENABLED=true`, the application will attempt to start the gRPC server (default port: `30000`).
+    - When absent or set to anything other than `true`, the gRPC server will not be started.
+- **Example (shell):**
+
+```bash
+export GRPC_ENABLED=true
+```
+
+- **Example (Docker Compose):**
+
+```yaml
+environment:
+  - GRPC_ENABLED=true
+```
+
+- **Notes / Best practices:**
+    - Treat the value as a simple on/off toggle. To avoid ambiguity, set explicitly to `true` or `false`.
+    - If you enable gRPC, make sure any required authentication (see `GRPC_PASSPHRASE`) is also configured.
+
+---
+
+### `GRPC_PASSPHRASE`
+
+- **Type:** String
+- **Default:** *no default* (empty / unset)
+- **Required if:** `GRPC_ENABLED=true`
+- **Purpose:** Shared secret used to authenticate gRPC clients. The application should validate that the passphrase is
+  present when gRPC is enabled and use it to verify client connections.
+- **Example (shell):**
+
+```bash
+export GRPC_PASSPHRASE="my-very-strong-passphrase"
+```
