+Sioyek is a PDF viewer with a focus on technical books and research
+papers. It uses the mupdf rendering library.
+
+Searchable
+  Quickly search your previously opened documents, table of contents,
+  bookmarks, and highlights. Sioyek can even generate the table of
+  contents if the document doesn't have one!
+
+Smart Jump
+  You can preview or jump to references (e.g. bibliography, figures,
+  equations, etc.) even when the document doesn't have links. You can
+  also search references in google scholar with one click!
+
+Portals
+  You can create portals from parts of documents to other parts which
+  are displayed in a second window. So when you are reading a paragraph
+  that is talking about a figure, table, algorithm, theorem, etc. you
+  don't have to keep jumping between the two locations.
+
+Marks and Bookmarks
+  Mark locations with one-character symbols and then quickly jump back
+  to them. You can also create bookmarks which are like marks, but use a
+  descriptive text instead of a symbol and can be searched.
+
+Highlights
+  Sioyek can highlight text with different colors. They are searchable!
+
+Command Palette
+  Discover sioyek commands and shortcuts using the searchable command
+  palette.
+
+Keyboard Focused
+  While sioyek fully supports many mouse actions, it is still possible
+  to use sioyek only using a keyboard. This includes functionality such
+  as text selection too!
+
+Synctex
+  Sioyek autoreloads the document so you can preview the changes as you
+  edit the latex file. You can also jump between the corresponding
+  locations in PDF and latex files with one click.
+
+Ruler
+  Use a visual ruler to highlight the line currently being read. It
+  reduces eye strain and combined with smart jump feature can create
+  previews and portals without needing to click on the reference!
+
+Configurable
+  Sioyek is highly configurable. You can change all the keybinds and
+  adjust the behavior of the application.
+
+Extensible
+  You can extend sioyek using external commands and scripts. For example
+  you can add OCR, translation, and text to speech to sioyek.

+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
