+  \section{\label{ref:SupportedMetadata}Supported metadata tags}
+    Rockbox supports different metadata formats. In general those tag formats
+    are ID3 (v1 and v2), APE (v1 and v2), Vorbis, MP4 and ASF. Few codecs use
+    codec specific tags, several codecs do not use any tags yet. The following
+    table gives an overview about what tag types rockbox supports for which
+    audio file extension.\\
+    \note{There is always only \textbf{one} tag type supported for each file
+    extension.}
