+# ![RealWorld Example App using Kotlin and Spring](example-logo.png)
+
+> ### Spring boot + MyBatis codebase containing real world examples (CRUD, auth, advanced patterns, etc) that adheres to the [RealWorld](https://github.com/gothinkster/realworld-example-apps) spec and API.
+
+This codebase was created to demonstrate a fully fledged fullstack application built with Spring boot + Mybatis including CRUD operations, authentication, routing, pagination, and more.
+
+For more information on how to this works with other frontends/backends, head over to the [RealWorld](https://github.com/gothinkster/realworld) repo.
+
+# How it works
+
+The application uses Spring boot (Web, Mybatis).
+
+# Security
+
+Integration with Spring Security and add other filter for jwt token process.
+
+The secret key is stored in `application.properties`.
+
+# Database
+
+It uses a H2 in memory database (for now), can be changed easily in the `application.properties` for any other database.
+
+# Getting started
+
+You need Java installed.
+
+    ./gradlew bootRun
+    open http://localhost:8080
+
+# Help
+
+Please fork and PR to improve the code.
