+</p>
+<pre>
+    import com.beust.kobalt.plugin.dokka.dokka
+    // ...
+
+    dokka {
+        args("-output", "markdown")
+        linkMapping {
+            dir = "src/main/kotlin"
+            url = "https://github.com/cy6erGn0m/vertx3-lang-kotlin/blob/master/src/main/kotlin"
+            suffix = "#L"
+        }
+    }
+</pre>
