+<title>Supported formats</title>
+
+<p>
+Atril supports the following formats:
+</p>
+<list>
+ <item><p>Comic Book Archive (.cbr and .cbz)</p></item>
+ <item><p>Device Independent file format (.dvi)</p></item>
+ <item><p>DjVu (.djvu, .djv)</p></item>
+ <item><p>Open XML Paper Specification (.oxps, .xps)</p></item>
+ <item><p>Portable Document Format (.pdf)</p></item>
+ <item><p>PostScript (.ps)</p></item>
+</list>
+<note>
+<p>
+In some Linux distributions, not all formats are supported by default, so you might not be able to view all the formats listed above.
+</p>
+<p>
+Support for a format is called a <em>backend</em>.  If you get the error "Unable to Open Document", you may wish to check whether the backend package for the format is installed.
