+FoodsoftUservoice
+=================
+
+Adds [uservoice](https://uservoice.com/) feedback form to foodsoft.
+
+
+Configuration
+-------------
+
+This plugin is configured in the foodcoop configuration in foodsoft's
+"config/app\_config.yml":
+
+```yaml
+  uservoice:
+
+    # find the api key in your uservoice admin settings
+    api_key: Abc1234DefGhIjkl567MnoPQr
+
+    # https://developer.uservoice.com/docs/widgets/options/
+    set:
+      accent_color: '#448dd6'
+      trigger_color: white
+      trigger_background_color: rgba(46, 49, 51, 0.6)
+    addTrigger:
+      mode: contact
+      trigger_position: bottom-left
+
+    # Tell uservoice about the current user; only keys listed will be sent,
+    # when id, email, name or created_at has an empty value, get them from
+    # the current user.
+    identify:
+      id:
+      #email:
+      #name:
+      created_at:
+      #type: ExampleFoodcoopType
+```
+
+This plugin also introduces the foodcoop config option `use_uservoice`, which
+can be set to `false` to disable uservoice integration. May be useful in
+multicoop deployments.
+
+This plugin is currently missing a configuration screen.
+
+See also the [uservoice-widget documentation](http://rubydoc.info/gems/uservoice-widget).
