+## Adding links to the primary navigation menu
+The studyplan plugin will automatically add links to the flat navigation bat used in Moodle 3.11 and below
+However, Moodle 4.0-4.2 use a new "primary navigation" bar, and does not yet support customizing the primary navigation bar (it is a planned feature though)
+
+**Use the following workaround:**
+You can add custom primary menu items in **Site administration** -> **Appearance** -> **Theme settings**
+That page contains an item called  "Custom menu items"
+Add the following into that area to custimize it
+	//    [your name for my studyplan]|/local/treestudyplan/myreport.php
+	//    [your name for studyplan viewing]|/local/treestudyplan/view-plan.php
+	//    [your name for studyplan managing]|/local/treestudyplan/edit-plan.php
+	// For example:
+```
+Mijn studieplan|/local/treestudyplan/myreport.php||nl
+Studieplannen|/local/treestudyplan/view-plan.php||nl
+Studieplannen beheren|/local/treestudyplan/edit-plan.php||nl
+My study plan|/local/treestudyplan/myreport.php||en
+Study plans|/local/treestudyplan/view-plan.php||en
+Manage Study plans|/local/treestudyplan/edit-plan.php||en
+```
