This document is the "top sheet" (hence the name) for the project. A board in Altium consists of one or more "sheets," pages of the electrical schematic. They are arranged hierarchically - every design with more than one sheet needs a "top" sheet and then "subsheets," which can be nested an arbitrary number of times (subsheets can have subsheets, which can have subsheets, which can have subsheets...) The green box (known as a "sheet symbol") represents a subsheet, containing the schematic for an Arduino microcontroller. You can open that sheet either from the Projects panel or by hitting {{altium-shortcut|ctrl + double click}} on the sheet symbol.

We won't need to edit the subsheet for this project, but it may prove helpful to look at as an example of what an Altium schematic can look like.

We'll make one small edit to the subsheet for this project, and it may prove helpful to look at as an example of what an Altium schematic can look like.
