+
+== Installation
+
+=== Build
+
+Run the following command to construct a jar with dependencies.
+

+== Command-line Interface
+
+Run the client via
+
+----
+java -jar path/to/morphviz.jar
+----
+
+=== Usage

+java -jar morphviz.jar -i rules.xml > rules.dot
+----
+
+== Appendix
+
+=== Create PDF from DOT-File
+
+* Install https://www.graphviz.org/download/[GraphViz]
+* Run `dot -Tpdf rules.dot -o rules.pdf`
+
+Note::
+This applies also to any other target format provided by graphviz.
+
+=== Visualize DOT-File online
+
+* Open link:https://dreampuf.github.io/GraphvizOnline/[GraphvizOnline]
+* Copy the content of the generated DOT-File
