+== Dependency Injection
+
+This example shows how Camel JBang can use dependency injection annotations
+from Spring Boot or Quarkus, to wire up Java beans.
+
+The runtime is still plain Camel Main with JBang, and not Spring Boot or
Quarkus.
+However the benefit of allowing to use their annotations is that the transition
+from Camel JBang to Spring Boot or Quarkus is easier.
+
+
+=== 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 *
+----
+
+
+=== Live reload
+
+You can run the example with reload enabled which allows you to edit the
example,
+and hot-reload when the file is saved.
+
+[source,sh]
+----
+$ camel run * --reload
+----
+
+
+
+=== Help and contributions
+
+If you hit any problem using Camel or have some feedback, then please

+
+We also love contributors, so
+https://camel.apache.org/community/contributing/[get involved] :-)

+The Camel riders!
