 You only need to tell Asciidoctor where the templates are located and which template engine you're using.
 (Technically, you don't need to specify the template engine.

+However, by doing so, it makes the scan more efficient and deterministic.)
 
 If you're using the CLI, you specify the template directory using the `-T` option (longhand: `--template-dir`) and the template engine using the `-E` option (longhand: `--template-engine`).

+When using JRuby, you can refer to a directory on the classpath by prefixing the path with `uri:classloader:`.
+For example:
