+\subsection{Title slide: QR code and additional logos}{
+
+Three optional yaml entries personalise the title slide for external
+audiences (ported from \pkg{posterdown.ids}):
+\itemize{
+\item \verb{website: <url>} -- a linked QR code pointing to the URL is placed in
+the top left of the title slide. Uses the \pkg{qrcode} package.
+\item \verb{partner_logo: <path-or-url>} -- when a presentation is given by
+authors from two institutions, the partner institution's logo is shown
+next to the IDS logo, in the top right of every slide.
+\item \verb{funder_logo: <path-or-url>} -- a funder logo (e.g. "Text+") is placed
+in the bottom left of the title slide, opposite the Leibniz
+Gemeinschaft membership logo. It is lifted above the footer band on
+print (pdf) pages.
+}
+
+Local logo files (svg, png, jpg, gif, webp) are embedded in the html as
+data URIs, so they do not need to be shipped with the presentation; http
+URLs are used as-is. A QR code anywhere else on a slide can be produced
+with \code{\link[=qrlink]{qrlink()}} from inline R code. The navigation chrome (arrows, slide
+number, menu button) is hidden on the title slide for a bare first
+impression.
