+*******************
+Installing freedesktop.org icons
+*******************
+
+Exactly where to place icons varies depending on the Linux distribution and the
+desktop environment theme. These instructions worked for Pop!_OS, an Ubuntu
+spinoff. In general you should search for similar files in order to figure out what
+directory to place the icons in. Text you may have to change is in red.
+
+These instructions assume you want to install system-wide in ``/opt``.  You can avoid
+the need for ``sudo`` by instead installing somewhere in your home directory, using
+that directory instead of ``/opt`` and using ``~/.local`` instead of ``/usr``.
+
+**Extract the downloaded ``.tar.xz`` file into a directory in ``/opt``**
+
+   .. code-block:: sh
+
+      sudo mkdir /opt
+      cd /opt
+      sudo tar -xf ~/Downloads/blender-'4.0.2-linux-x64'.tar.xz
+
+**Add a symbolic link to skip the version number**
+
+   .. code-block:: sh
+
+      sudo rm /opt/blender
+      sudo ln -s blender-'4.0.2-linux-x64' /opt/blender
+
+**Make running blender from the command line work**
+
+   .. code-block:: sh
+
+      sudo ln -s /opt/blender/blender /usr/bin/blender
+      sudo ln -s /opt/blender/blender-thumbnailer /usr/bin/blender-thumbnailer
+
+   You should now be able to type ``blender`` in a shell to run it.
+
+**Make the desktop know about the blender application**
+
+   .. code-block:: sh
+
+      sudo ln -s /opt/blender/blender.desktop /usr/share/applications/
+
+   It should now appear in your Application selector, but the icon is missing.
+
+**Make the icon for the blender application work**
+
+   .. code-block:: sh
+
+      sudo ln -s /opt/blender/blender.svg /usr/share/icons/'hicolor/'scalable/
+
+**Check if the "mime type" exists**
+
+   This may be true of any modern Linux install.
+
+   .. code-block:: sh
+      :emphasize-lines: 2
+
+      mimetype foo.blend
+      foo.blend: application/x-blender
+
+   Alternative:
+
+   .. code-block:: sh
+      :emphasize-lines: 2
+
+      grep blender /etc/mime.types
+      application/x-blender				blend
+
+**Add the mimetype if missing**
+
+   Put the following into ``/usr/share/mime/packages/Overrides.xml``:
+
+   .. code-block:: xml
+
+      <?xml version="1.0" encoding="UTF-8"?>
+      <mime-info xmlns="http://www.freedesktop.org/standards/shared-mime-info">
+        <mime-type type="application/x-blender">
+          <comment>Blender scene</comment>
+          <glob pattern="*.blend"/>
+          <sub-class-of type="text/plain"/>
+        </mime-type>
+      </mime-info>
+
+   And run this:
+
+   .. code-block:: sh
+
+      sudo update-mime-database /usr/share/mime
+
+**Make the icon for .blend files work**
+
+   .. code-block:: sh
+
+      sudo ln -s /opt/blender/blender-symbolic.svg \
+          /usr/share/icons/'Pop/'scalable/mimetypes/application-x-blender.svg
+      sudo update-icon-caches /usr/share/icons/'Pop/'
+
+**Make thumbnails work for .blend files**
+
+   Put the following into ``/usr/share/thumbnailers/x-blender.thumbnailer``:
+
+   .. code-block:: ini
+
+      [Thumbnailer Entry]
+      TryExec=/usr/bin/blender-thumbnailer
+      Exec=/usr/bin/blender-thumbnailer %i %o
+      MimeType=application/x-blender;
