How to roll a d20 (and the rest)
Click d20 then Roll dice, or type 1d20. Notation is NdS or NdS+M: number of dice, sides, optional modifier. Examples: 1d20, 2d6+3, 4d6. The roller caps a single roll at 20 dice so a typo cannot hang the page.
4d6 drop lowest rolls four six-sided dice, discards the lowest, and sums the other three — the usual D&D 5e ability-score method. History stays on the page so you can compare a set of scores. For a binary choice, use the coin flip instead of a d2.
