+GNOME JPEG EXIF Thumbnailer
+===========================
+Fast GNOME thumbnailer for JPEG files that uses the embedded EXIF thumbnail from
+the source file, if present. Greatly speeds up thumbnail generation when
+browsing a folder of images shared over a network.
+
+Installation
+------------
+1. Install `exiftool` and `libimage-exiftool-perl` using your package manager.
+2. Execute `./install` which automatically runs the steps below.
+
+Manual Installation
+-------------------
+1. Copy the `jpeg-exif-thumbnailer` script to `/usr/bin/` .
+2. Copy the `jpeg-exif.thumbnailer` definition to `/usr/share/thumbnailers` .
+3. Edit `/usr/share/thumbnailers/gdk-pixbuf-thumbnailer.thumbnailer` and remove
+   `image/disabled-jpeg` from the list of MIME types.
+
+Uninstallation
+--------------
+Execute `./uninstall` which automatically reverts the steps above.
