+# Basic Flow
+http request -> controller -> service -> repository -> return to parent callers -> http response
+
+# Quick start
+## Start from scratch and run the APIs on your local system
+1. Take a pull from the main branch by cloning the repo in your local system
+2. Make sure you've got mvn installed with version 3.5+ with `mvn -version`
+3. Make a JAR by `mvn clean install` command to be used for deploying or testing
+4. Use `-DskipTests` to skip the tests while running any mvn command to reduce package time
+
+## running the ready-to-go JAR (or use the JAR you created above)
+1. Download the jar from the releases https://github.com/COMP8117-2021S-Team09/backend/releases
+2. Make sure you have java installed with version 8 (preferable) - check version `java -version`
+3. Run the `java -jar first_release_1-0.0.1-SNAPSHOT.jar` command where you have kept the JAR (assuming you are in home location and have not changed the JAR name)
+4. Open the link http://localhost:8080/ and the API docs should open up where you can try out the APIs
