Unclear where custom template should reside

The documentation on the page http://developer.lightbend.com/docs/paradox/latest/features/theming.html#create-local-templates is not working. I have this build.sbt:

name := "Foo Bar"
scalaVersion := "2.12.1"
enablePlugins(ParadoxSitePlugin)
paradoxTheme := None

But when I run sbt previewSite, it doesn’t find the template:

java.lang.RuntimeException: StringTemplate 'page' was not found for '/home/hhrutz/IEM/Projektantraege2014/website/target/paradox/paradox/html/index.html'. Create a template or set a theme that contains one.
	at scala.sys.package$.error(package.scala:27)
	at com.lightbend.paradox.template.PageTemplate.write(PageTemplateSystem.scala:55)

I have copied the generic theme:

$ ls -la src/main/paradox/_template/

Yes, paradoxProperties has to be scoped using Paradox instead of Compile with the sbt-site plugin:

paradoxProperties in Paradox ++= Map(
  "extref.rfc.base_url" -> "http://tools.ietf.org/html/rfc%s"
)

Oh ok, I see, ParadoxSitePlugin uses src/paradox instead of src/main/paradox, but now it doesn’t pick up paradoxProperties. So these are other problems now, closing the issue.
