+== Hello Java
+
+This example shows how beans defined directly in Java source code can be added to Camel registry using XML and YAML DSLs.
+
+Camel 4 is required.
+
+=== Install JBang
+
+First install JBang according to https://www.jbang.dev
+
+When JBang is installed then you should be able to run from a shell:
+
+[source,sh]
+----
+$ jbang --version
+----
+
+This will output the version of JBang.
+
+To run this example you can either install Camel on JBang via:
+
+[source,sh]
+----
+$ jbang app install camel@apache/camel
+----
+
+Which allows to run CamelJBang with `camel` as shown below.
+
+=== How to run
+
+Then you can run this example using:
+
+[source,sh]
+----
+$ camel run StandaloneGreeter.java beans.yaml app.xml
+----
+
+Or run with JBang using the longer command line (without installing camel as app in JBang):
+
+[source,sh]
+----
+$ jbang camel@apache/camel run StandaloneGreeter.java beans.yaml app.xml
+----
+
+=== Live reload
+
+You can run the example in dev mode which allows you to edit the example,
+and hot-reload when the file is saved.
+
+[source,sh]
+----
+$ camel run StandaloneGreeter.java beans.yaml app.xml --dev
+----
+
+=== Run directly from github
+
+The example can also be run directly by referring to the github URL as shown:
+
+[source,sh]
+----
+$ jbang camel@apache/camel run https://github.com/apache/camel-kamelets-examples/tree/main/jbang/app-routes-beans
+----
+
+=== Developer Web Console
+
+You can enable the developer console via `--console` flag as show:
+
+[source,sh]
+----
+$ camel run StandaloneGreeter.java beans.yaml app.xml --console
+----
+
+Then you can browse: http://localhost:8080/q/dev to introspect the running Camel applicaton.
+Under "beans" Camel should display `greeter1` and `greeter2` beans.
+
+
+=== Help and contributions
+
+If you hit any problem using Camel or have some feedback, then please
+https://camel.apache.org/community/support/[let us know].
+
+We also love contributors, so
+https://camel.apache.org/community/contributing/[get involved] :-)
+
+The Camel riders!
