+# Todo Web Application using Spring Boot and H2 In memory database
+
+Run com.nisum.springboot.web.SpringBootFirstWebApplication as a Java Application.
+
+Runs on default port of Spring Boot - 8080 
+
+## Can be run as a Jar or a WAR
+
+`mvn clean install` generate a war which can deployed to your favorite web server.
+
+We will deploy to Docker as a WAR
+
+## Web Application
+
+- http://localhost:8080/login with in28minutes/dummy as credentials
+- You can add, delete and update your todos
+- Spring Security is used to secure the application
+- `com.nisum.springboot.web.security.SecurityConfiguration` contains the in memory security credential configuration.
+
+## H2 Console
+
+- http://localhost:8080/h2-console
+- Use `jdbc:h2:mem:testdb` as JDBC URL 
+
