+@chapter Local files
+
+Elpher supports opening local files via @code{file:} URLs.
+
+For instance, pressing @key{g} and entering @code{file:~/document.gmi}
+will load the file named @samp{document.gmi} in your home directory,
+provided this file exists.
+
+Files opened in this way are rendered according to their name, and in
+particular their extension.  The current mappings are as follows:
+
+@table @asis
+
+@item @samp{txt}
+
+Plain text documents.  All local text files are assumed to be
+UTF-8-encoded.
+
+@item @samp{gemini},@samp{gmi}
+
+Gemini documents (i.e. documents of MIME type ``text/gemini'').  All
+local gemini files are assumed to be UTF-8-encoded.
+
+@item @samp{html},@samp{htm}
+
+HTML documents.  All local HTML files are assumed to be UTF-8-encoded.
+
+@item @samp{png},@samp{jpg},@samp{jpeg},@samp{gif},@samp{bmp},@samp{tif},@samp{tiff}
+
+Image files.
+
+@item Anything else
+A binary document, which elpher will simply offer to save somewhere
+else. (Obviously this is not useful in its own right, but there's not
+much that elpher can sensibly do with unknown binary files.)

+
+Like other browsers, elpher makes certain internally-generated pages
+such as the initial welcome page, the bookmarks page, the history
+stack and the list of visited pages pages accessible as URLs with
+the ``about:'' type.
+
+This means that these pages can be bookmarked and, more usefully,
+added to a local file to be rendered as a user-defined start page.

+One particularly important customization is the @code{elpher-start-page}

+@samp{about:welcome}, but any URL can be substituted.  For example, you

+of @code{elpher-start-page} to @samp{file:~/.emacs/start-page.gmi} to have
