A great website has a great menu, to easily navigate all the important pages.
Your community website comes with a few default menu items.

Per menu item you can set if it should open in a new window, or if it should show up in your menu at all.

There are a couple default pages, that you can easily add to your menu by clicking "Add to menu". All the pages you created will available to add to the menu.
You can also add links to other websites, like your Discord channel. To do this, please use the 'Add custom' form at the bottom (blue).

Do not forget to save your menu when you are done changing.
