As noted in subject line that the rules summary is missing how the well is used.

Principal Actions (should actually be called “the grounds area”or even “the grounds area actions” since the rule book classifies it as such)
Gardener Choose a garden card without one of your gardeners, pay the cost in food to place and activate the card. This card will activate again if there is a die left above it at the end of the round.
Courtier Either, Pay 2 coins to place a courtier in the courtyard, AND/OR Pay 2 or 5 mother of pearl resources to move a courtier up 1 or 2 levels. If your courtier ends on the top level of the castle gain a lantern award (your player boards tucked cards) and place your courtier on an empty bonus space. Otherwise on level 1 and 2 pick a card to take and do one of the light banner actions, then it will flip over and add to your future lantern actions.
Warrior Choose any yard (top right corner) and pay the iron resource costs to place a warrior and gain the rewards. These will also multiply your score for your courtiers in the castle at the end of the game.
The Well should be listed at this point.
