Configuration
=============
Many aspects of the behaviour of MKWS can be modified by setting
-parameters into the `mkws_config` object. **This must be done *before*
-including the MKWS JavaScript** so that when that code is executed it
-can refer to the configuration values. So the HTML header looks like
-this:
+parameters into the `mkws_config` object. So the HTML header looks
+like this:
+
+The Facet template has a special feature where you can override it on a
+per-facet basis by adding a dash and the facet name as a suffix eg.
+`facet-subjects` rather than `facet`. (So `class="mkws-template-facet-subjects"`)
+
+You can also explicitly specify a different template for a particular instance
+of a widget by providing the name of your alternative (eg. SpecialPager) as the
+value of the `template` key in the MKWS config object for that widget:
+for example, ``.
+
+Templates for MKWS can also be
+[precompiled](http://handlebarsjs.com/precompilation.html). If a precompiled
+template of the same name is found in the `Handlebars.templates` object, it
+will be used instead of the default.
+
+Inspecting metadata for templating
+----------------------------------
+
+MKWS makes requests to Service Proxy or Pazpar2 that perform the actual
+searching. Depending on how these are configured and what is available from the
+targets you are searching there may be more data available than what is
+presented by the default templates.
+
+Handlebars offers a convenient log helper that will output the contents of a
+variable for you to inspect. This lets you look at exactly what is being
+returned by the back end without needing to use a Javascript debugger. For
+example, you might prepend `{{log hits}}` to the Records template in order to
+see what is being returned with each search result in the list. In order for
+this to work you'll need to enable verbose output from Handlebars which is done
+by including this line or similar:
+
+
+
+Internationalisation
+--------------------
-* `mkwsTemplate_Record` -- used when displaying a full record.
+If you would like your template to use the built in translation functionality,
+output locale specific text via the mkws-translate helper like so:
+`{{{mkws-translate "a few words"}}}`.
-For both of these the metadata record is passed in, and its fields can
-be referenced in the template. As well as the metadata fields
-(`md-*`), two special fields are provided to the `mkwsTemplate_Summary`
-template, for creating popup links for full records. These are `_id`,
-which must be provided as the `id` attribute of a link tag, and
-`_onclick`, which must be provided as the `onclick` attribute.
+Example
+-------
-For example, an application can install a simple author+title summary
-record in place of the usual one providing the following template:
+Rather than use the included AJAX helpers to render record details inline,
+here's a Records template that will link directly to the source via the address
+provided in the metadata as the first element of `md-electronic-url`:

+[Bootstrap](http://getbootstrap.com/) classes and a custom Handlebars helper is
+employed, take a look at the source of

-Responsive design
------------------
-Metasearching applications may need to appear differently on
-small-screened mobile devices, or change their appearance when
-screen-width changes (as when a small device is rotated). To achieve
-this, MKWS supports responsive design which will move the termlists to
-the bottom on narrow screens and to the sidebar on wide screens.
+Refinements
+===========
-To turn on this behaviour, set the `responsive_design_width` to the desired
-threshhold width in pixels. For example:
-
+Message of the day
+------------------
-If individual result-related components are in use in place of the
-all-in-one mkwsResults, then the redesigned application needs to
-specify the locations where the termlists should appear in both
-cases. In this case, wrap the wide-screen `mkwsTermlists` element in a
-`mkwsTermlists-Container-wide` element; and provide an
-`mkwsTermlists-Container-narrow` element in the place where the narrow-screen
-termlists should appear.
+Some applications might like to open with content in the area that
+will subsequently be filled with result-records -- a message of the
+day, a welcome message or a help page. This can be done by placing an
+`mkwsMOTD` division anywhere on the page. It will be moved into the
+`mkwsResults` area and initially displayed, but will be hidden when a
+search is made.
