+Why?
+
+- avoid deploying wkhtmltopdf and it's dependencies in your application image
+- keep the memory requirement of your application pods low while delegating
+  memory hungry wkhtmltopdf jobs to dedicated pods
+- easily select the wkhtmltopdf version to use at runtime

+# WARNING
+
+The server is not meant to be exposed to untrusted clients.
+
+Several attack vectors exist (local file access being the most obvious).
+Mitigating them is not a priority, since the main use case is
+to use it as a private service.
