Select the Site Info tool from the Tool Menu of your site.

As you select tools from the General list on the left side of the screen, they are added to the Selected tools list on the right side of the screen. The right side of the screen displays the tools you have selected.  

In addition, you can enable Lessons subpage navigation in the left tool menu by checking the box. See How do I enable Lessons subpage navigation in the Tool Menu? for more information.

For some tools such as Lessons and Web Content, you can add multiple instances of the tool.

The Lessons tool may be used as a single tool on the Tool Menu where students click to see all Lessons, or there can be multiple Lessons tools added to the Tool Menu so that each tool is a separate Lesson. See the Lessons help documentation for more information.

The Web Content tool points to any URL you enter and you may create as many of these as you want.

Click on the More Lessons Tools? or More Web Content Tools? drop-down menus to add additional instances of these tools.

Once you have made all of your tool selections, scroll down and click the Continue button to save your edits.

New tools added are shown in red font. Confirm that these are tools you want to add and click the Finish button. New tools are typically added to the bottom of the Tool Menu once you save your changes.  See the How do I rearrange or rename the items in the Tool Menu? tutorial for instructions on how to change the tool order.
