     _Anyone who tries to use Moodle now will receive a maintenance message._
 
+    **Note:** If the outage starts with the option `Auto start maintenance mode` checked, the maint mode won't exit automatically.
+    It will need to be disabled through command line.
+
 1) Perform the maintenance activities.
 
     At this point it is safe to perform the required maintenance as no one can use the system, not even admins.

+Custom Theme Additional SCSS
+-------------------
+
+Custom themes generally do not have the same `$navbar-height` variable set to 80px (MOODLE), therefore custom themes will not calculate the change in navbar height with page elements that calculate the navbar total height. 
+
+Add the following SCSS For Moodle 3.11+
+
+```
+body.auth_outage {
+    #page-wrapper {
+        #nav-drawer {
+            top: $navbar-height + 100px;
+            height: calc(100% - (#{$navbar-height} + 100px));
+        }
+        #page {
+            margin-top: $navbar-height + 100px;
+        }
+    }
+    [data-region=right-hand-drawer].drawer {
+        top: $navbar-height + 100px;
+        height: calc(100% - (#{$navbar-height} + 100px));
+    } 
+}
+```
+
+Totara is a little different with version 13+ and no variables are used to set the `totaraNav` height 
+
+Add the following CSS For Totara 13+
+
+```
+.totaraNav {
+    margin-top: 100px;
+}
+.local_envbar .totaraNav {
+    margin-top: 50px;

 How to use
 ----------
@@ -141,6 +183,18 @@ Why it is an auth plugin?
 
 One of the graduated stages this plugin introduces is a 'tester only' mode which disables login for most normal users. This is conceptually similar to the maintenance mode but enables testers to login and confirm the state after an upgrade without needing full admin privileges. 
 
+Tester restriction options
+------------
+Two options are available to restrict the site to only let testers in during the tester phase.
+Note: these restrictions build on each other; If both are enabled, users must meet both criteria to be allowed in.
+
+## IP restriction
+Only allow users from a certain IP or range of ips to enter.
+## Access key
+Users provide an access key in the URL params on first page load, which is then stored as a cookie for 24 hours. If the access key matches the one setup for the outage, they are allowed in.
+## Using IP restriction with access key
+Users will be allowed if they are from the configured allowed ips OR if they provide the correct access key.

+Feature: Disable warning bar in embedded layout
+  In order alert users about an outage
+  As any user
+  I need to view the warning bar, but not in embedded layout
+
+  Background:
+    Given the authentication plugin "outage" is enabled
+    And the following "courses" exist:
+      | fullname | shortname |
+      | Course 1 | C1 |
+    And the following "activities" exist:
+      | activity | name       | intro      | introformat | course | content  | contentformat | idnumber |
+      | page     | PageName1  | PageDesc1  | 1           | C1     | H5Ptest  | 1             | 1        |
+    And the "displayh5p" filter is "on"
+
+  Scenario: Disable warning bar in embedded h5p in book activity
+    Given I log in as "admin"
+    And I am on "Course 1" course homepage with editing mode on
+    And I add a "File" to section "1"
+    And I set the following fields to these values:
+      | Name | ipsumFile |
+    And I upload "h5p/tests/fixtures/ipsums.h5p" file to "Select files" filemanager
+    And I press "Save and return to course"
+    And I follow "PageName1"
+    And I navigate to "Edit settings" in current page administration
+    And I click on "Insert H5P" "button" in the "#fitem_id_page" "css_element"
+    And I click on "Browse repositories..." "button" in the "Insert H5P" "dialogue"
+    And I click on "Server files" "link" in the ".fp-repo-area" "css_element"
+    And I click on "ipsumFile (File)" "link"
+    And I click on "ipsums.h5p" "link"
+    And I click on "Select this file" "button"
+    And I click on "Insert H5P" "button" in the "Insert H5P" "dialogue"
+    And I wait until the page is ready
+    And I click on "Save and display" "button"
+    When there is the following outage:
+      | warnbefore | startsin |
+      | 0          | 0        |
+    And I reload the page
+    Then I should see "Back online at" in the warning bar
+    And I should not see "Lorum ipsum"
+#   Switch to iframe created by filter
+    And I switch to "h5p-iframe" class iframe
+    And I should not see the warning bar
+#   Switch to iframe created by embed.php page
