The first step to integrating a Credo course via LTI in your Moodle is to sign in as an instructor and under the "Administration" panel, click on "turn editing on."
Next, click on the "Add an Activity" dropdown menu within the week you want to add the item. From the dropdown, select "External Tool".
Under the External Tool Type, look at the drop down menu for "Automatic, based on luanch URL". If you it doesn't fit any existing settings, click on the plus icon to the right of the drop down menu to add the LTI settings for the Credo tool.
