+== Chaos Monkey
+
+This example shows a chaos moneky with Camel JBang.
+
+When everything is okay then Camel reports UP in the helath check.
+But the chaos monkey can from time to time cause problems and the health check
is then DOWN.
+
+
+=== 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 *
+----
+
+Or run with JBang using the longer command line (without installing camel as
app in JBang):
+
+[source,sh]
+----
+$ jbang camel@apache/camel run *
+----
+
+=== 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/chaos-monkey
+----
+
+=== Helath Check Console
+
+You can enable the health check console via `--health` flag as show:
+
+[source,sh]
+----
+$ camel run * --health
+----
+
+Then you can browse: http://localhost:8080/q/health to introspect the health
check
+of the running application. When the chaos moneky is causing problems then the
check is DOWN otherwise its UP.
+
+
+=== 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!
