-The Lua scripts in this repository are meant to be used together with darktable. Either copy them individually to `~/.config/darktable/lua` (you might have to create that folder) or just copy/symlink the whole repository there. That allows to update all your scripts with a simple call to `git pull`.

-To enable one of the scripts you have to add a line like `require "official/hello_world"` to your `~/.config/darktable/luarc` file which will enable the example script in `official/hello_world.lua` (note the lack of the `.lua` suffix).

+QUICKTAG
+   For faster attaching your favorite tags, the script adds shortcuts and
+   the module "quicktag" in lighttable mode with a changeable number of buttons.
+   To each button a tag can be assigned. If the tags do not exist in your database,
+   they are added to the database once they get the first time attached to an image.
+
+   The number of buttons/shortcuts can be changed in the lua preferences.
+   Changes in the number require a restart of darktable.
+
+INSTALATION
+   * copy this file in $CONFIGDIR/lua/ where CONFIGDIR is your darktable configuration directory
+   * add the following line in the file $CONFIGDIR/luarc require "quicktag"
+
+USAGE
+   * set the number of quicktags between 2 and 10 in the preferences dialog and restart darktable
+   * if wanted set the shortcuts in the preferences dialog
+   * to add or change a quicktag, first select the old tag with the combobox "old quicktag",
+     enter a new tag in the "new quicktag" filed and press "set quicktag"
+   * use a shortcut or button to attach the tag to selected images
