4. In another terminal window go to the same folder \MongoDB\Server\3.2\bin
5. Launch the MongoDB shell with command "mongo"
6. You can use command "help" to see available commands
7. Create user in the admin db use admin db.createUser( { user: "root", pwd: "root", roles: [{role: "root", db: "admin"},{role: "userAdminAnyDatabase", db: "admin"}] } )

** For building and launching application**

1. In the terminal window go to the project folder, use command "gradle clean build". "BUILD SUCCESSFUL" means that build is successful :)

3. Use command "java -jar gamification-1.jar"
4. The string "Started Gamification" means the successful start. Default port – 8080.
