+=== Downloading JARs over the internet
+
+By default, Camel JBang will automatically resolve dependencies needed to run
Camel, which is done
+by JBang and Camel respectively. Camel itself detects at runtime if a
component has a need for JARs that
+are not currently available on the classpath, and can then automatic download
the JARs (incl transitive).
+
+Camel will download these JARs in the following order:
+
+1. from local disk in `~/.groovy/grapes`
+2. from local disk in `~/.m2/repository`
+3. from internet in Maven Central
+4. from internet in custom 3rd-party Maven repositories
+
+If you do not want Camel JBang to download over the internet, you can turn
this off with `--download`, as shown below:
+
+[source,bash]
+----
+camel run foo.java --download=false
+----
+
+When Camel JBang download dependencies it will only report the top level
dependency being downloaded.
+You can enable verbose logging that will also log activity for each transitive
dependency,
+using the `--downloadVerbose` option as shown:
+
+[source,bash]
+----
+camel run foo.java --downloadVerbose=true
