At the Polar Cloud top menu, under “Help” (Figure 2.4 on narrow displays, or Figure 2.23 on large displays), click on “Documentation” to take you to a “DOCUMENTATION” screen, see Figure 2.24.
When there are multiple formats of a documentation item, e.g., PDF and HTML formats, the tile for that item of documentation will show buttons for viewing the alternate formats, e.g., “VIEW PDF” and “VIEW HTML”. Clicking on a button will open the selected item of documentation in a new window.
