 # gift-card-guard
-Manage gift cards, their current values, and an image of the most recent receipt
+Manage gift cards, their current values, and an image of the most recent receipt. Never forget
+how much a gift card is worth, or be unable to use a gift card because the proof of its
+value is lost.
+
+If there is any interest in improving this open source baby monitor, kindly submit a pull request with
+proposed changed.
