+[![Build Status](https://travis-ci.com/CodelyTV/cqrs-ddd-java-example.svg?branch=master)](https://travis-ci.com/CodelyTV/cqrs-ddd-java-example)
 
-1. Install Java 8
-2. Clone this repository `git clone https://github.com/CodelyTV/java-bootstrap`.
-3. Run the tests with `./gradlew test`
+Implementation example of a Java application following Domain-Driven Design (DDD) and Command Query Responsibility Segregation (CQRS) principles, keeping the code as simple as possible.
+
+Take a look, play and have fun with it!
+
+## 🚀 Environment setup
+
+1. Install Java: `brew cask install java`
+2. Clone this repository: `git clone https://github.com/CodelyTV/java-bootstrap`.
+3. Execute some [Gradle lifecycle tasks](https://docs.gradle.org/current/userguide/java_plugin.html#lifecycle_tasks) in order to check everything is OK:
+    1. Create [the project JAR](https://docs.gradle.org/current/userguide/java_plugin.html#sec:jar) and other project artifacts:
+    `./gradlew assemble --warning-mode all`
+    2. Run the tests and plugins verification tasks:
+    `./gradlew check --warning-mode all`
 4. Start developing!
+
+## 🤔 How to update dependencies
+
+* Gradle (current version: 5.1.1 - [releases](https://gradle.org/releases/)):
+`./gradlew wrapper --gradle-version=5.1.1 --distribution-type=bin` or modifying the [gradle-wrapper.properties](gradle/wrapper/gradle-wrapper.properties#L3)
+* JUnit (current version: 5.3.2 - [releases](https://junit.org/junit5/docs/snapshot/release-notes/index.html)):
+[`build.gradle:11`](build.gradle#L11-L12)
