The init sub-command can be used to simplify creating Kamelets. Through this
command, it is possible to create new Kamelets through pre-configured
templates. It works in two steps: first it is necessary to bootstrap the
Kamelet by creating a properties file with the parameters necessary to create
the Kamelet. Once the properties file is correctly set, then it is possible to
create a pre-filled Kamelet by processing that properties file.

+== Init Bindings
+
+The init sub-command can also be used to simplify creating Kamelets bindings.
Through this command, it is possible to create new bindings through
pre-configured templates. Use the `--kamelet` option (you can list the
available ones using the search command) to set the Kamelet to generate the
binding for.
+
+To execute this feature run:
+
+[source,bash]
+----
+CamelJBang init binding --destination /path/to/destination/directory/
--kamelet sftp-source
+----
+
+This will create a new sample YAML binding file that can be modified and used
in Camel K.
+
+You can also generate bindings that can be run by CamelJBang or Camel Core,
but setting the `--project` option:
+
+[source,bash]
+----
+CamelJBang init binding --destination /path/to/destination/directory/
--kamelet sftp-source --project core
