 Spring Boot REST Service to provide a REST API replacement to current Sarapis OR Service.
 
 ## To run the database
+Copy the environment variables from the `.env` file.
+```bash
+cp .env.example .env
+```
+
+Start the db container with the following command
 ```bash
 docker-compose up
 ```
+In your terminal you will find the logs of the database. If you see 
+the following log the database has started gracefully.
+```
+LOG:  database system is ready to accept connections
+```
+
+To shut down the container database use
+```bash
+docker-compose down
+```
 
 ## To run the service
+Build the Java service. This command will generate the application `jar` inside
+the `target` directory.
+```bash
+mvn clean install
+```
+If the build is successful, then run the service
 ```bash
 java -jar target/orservice-0.0.1-SNAPSHOT.jar
+```
+You will start seeing logs from the service booting up. If you see the following log
+```
+Started OrserviceApplication in {} seconds (process running for {})
+```
+the service has started successfully.
+
+## Troubleshooting
+If the db has not started successfully do the following:
+1. Check that the container is running
+```bash
+docker ps
+```
+You should see all the containers running in your machine. 
+
+2. Try rebuilding the database
+```bash
+docker-compose down --volumes
+rm -rf postgres_data
+docker-compose up --build
 ```
