+# UMLGraph - Declarative Drawing of UML Diagrams
+
+*UMLGraph* allows the declarative specification and drawing of UML diagrams.
+You can browse the system's documentation
+through [this link](http://www.spinellis.gr/umlgraph/doc/index.html),
+or print it through [this link](http://www.spinellis.gr/umlgraph/doc/indexw.html).
+
+In order to run *UMLGraph*, you need to have [GraphViz](https://www.graphviz.org/)
+installed in your system path. On most Linux distributions, this can be easily
+installed using the regular package manager.
+
+To compile the Java doclet from the source code run *ant* on the
+*build.xml* file.
+
+If you change the source code, you can run regression tests by
+executing *ant test*.
+
+Visit the project's [home page](http://www.spinellis.gr/umlgraph) for more information.
+
+## Compatibility
+
+If you build against Java 8, please use latest version of 5.X of the Doclet.
+
+Since Java 9 doclet APIs where completely rewritten, the Doclet in version 6 supports only supports Java 9 and above.
+
+## Development versions
+
+In order to use development versions, you can use [JitPack](https://jitpack.io/#dspinellis/UMLGraph/master-SNAPSHOT).
+Note that as this is compiled on demand, you may sometimes see a "Read timed out" when the package is recompiled,
+and it should be fine a few seconds later. And because the master branch can change any time, you may want to use
+a versioned snapshot instead (see the Jitpack documentation for details).
+
+**Gradle**:
+```
+repositories { maven { url 'https://jitpack.io' } }
+configurations { umlgraph }
+dependencies { umlgraph 'com.github.dspinellis:UMLGraph:master-SNAPSHOT' }
+javadoc {
+  doclet = 'org.umlgraph.doclet.UmlGraphDoc'
+  docletpath = configurations.umlgraph.files.asType(List)
+  tags("hidden:X", "opt:X", "has:X", "navhas:X", "assoc:X", "navassoc:X",
+       "composed:X", "navcomposed:X", "stereotype:X", "depend:X")
+}
+```
+
+**Maven**:
+```
+<repositories>
+    <repository>
+        <id>jitpack.io</id>
