If you have your own site documentation then you can set this as the default by going to Quick-access menu > Appearance > Documentation. You can also configure the behaviour of documentation links, such as opening in a new window.
|Docs document root|
Change the default path to your own custom online documentation.
If the Docs document root field is left blank, the Docs for this page links will not appear.
|Language for docs||This language will be used for links to the documentation pages.||-|
|Open in new window||You may find that trainers prefer the documentation to open in a new window, so they can easily return to their page in Totara. If so, click the Open in new window checkbox.||-|
