 # Getting Started
+Depending on you would like to use the version 2.x.x (recommended as the latest version) or 1.x.x 
+there are 2 different ways of importing dependencies.
+
+## Version 2.x.x
+
+The Power Flows DMN can be imported as a dependency via:
+
+### Maven
+```xml
+<dependency>
+    <groupId>org.powerflows</groupId>
+    <artifactId>dmn-engine</artifactId>
+    <version>2.0.0</version>
+</dependency>
+```
+Since in version 2.0.0 Power Flows DMN has been divided into modules,
+a developer can decide what features have to be imported to his project. 
+Therefore, the first decision will be which modeling format of decision tables to be supported. 
+There is a choice between:
+* YAML file - requires **dmn-io-yaml** dependency
+* XML file - requires **dmn-io-xml** dependency
+* Java/Groovy file (fluent and functional) - delivered with **dmn-engine** dependency. In order to use Groovy style, dependency to Groovy is required as well.
+* Kotlin DSL - requires **dmn-kotlin-dsl** dependency
+
+**Surely, Power Flows DMN supports all of them within a single application!.**
+
+The next step is to add dependencies of expression evaluation languages. 
+The developer can use the all of some of them:
+* Literals - delivered with **dmn-engine** dependency
+* FEEL - requires **dmn-feel-evaluation-provider** dependency
+* JUEL - requires **dmn-juel-evaluation-provider** dependency
+* Groovy - requires **dmn-groovy-evaluation-provider** dependency
+* MVEL - requires **dmn-mvel-evaluation-provider** dependency
+* JavaScript - requires **dmn-javascript-evaluation-provider** dependency
+
+Optional dependencies:
