-Quick steps
+---
 
-Build the image with Docker (from repository root):
+## Quick Commands
 
 ```bash
+# Build Docker image
 docker build -t im-app:latest .
-```
 
-Run the image:
-
-```bash
-docker run --rm -p 8080:8080 \
-  -e SPRING_DATASOURCE_URL='jdbc:mysql://<host>:3306/imdb' \
+# Run the Docker image
+docker run --rm -p 8082:8082 \
+  -e SPRING_DATASOURCE_URL='jdbc:mysql://<host>:3306/inventory_db?useSSL=false&allowPublicKeyRetrieval=true&serverTimezone=UTC' \
   -e SPRING_DATASOURCE_USERNAME=root \
-  -e SPRING_DATASOURCE_PASSWORD=example \
+  -e SPRING_DATASOURCE_PASSWORD=Anjana@3176 \
   im-app:latest
-```
-
-Use docker-compose for local development (builds image and starts MySQL):
 
-```bash
+# Start using Docker Compose
 docker compose up --build
-```
 
-Notes
-- The Dockerfile uses Maven to build and OpenJDK 21 runtime to run the jar.
-- The `docker-compose.yml` exposes MySQL on 3306 for convenience. In production you should not expose DB ports publicly and use secure credentials.
-- If you want Docker image layers to cache better during development, consider copying only `pom.xml` first and running `mvn dependency:go-offline` before copying source.
