If you need to change the number of brands displayed on the Home page...

 

 

...navigate to CMS Desk -> Content and choose the Home page from the content tree. Switch to Edit -> Design and modify the Select top N property of the Brands web part, which displays the list of brands.

 

 

Alternatively, you may wish to change the layout of the displayed brand items by modifying properties in the Layout section of the web part.

 

If you now view the Home page on the live website, you can see that the number of displayed brands has changed and that it corresponds to the current value of the Select top N property of the Brands web part.
