+// You can define custom product info from build flags.
+// This is useful to allow API consumer to identify what type of WLED version
+// they are interacting with. Be aware that changing this might cause some third
+// party API consumers to consider this as a non-WLED device since the values
+// returned by the API and by MQTT will no longer be default. However, most
+// third party only uses mDNS to validate, so this is generally fine to change.
+// For example, Home Assistant will still work fine even with this value changed.
+// Use like this:
+// -D WLED_BRAND="\"Custom Brand\""
+// -D WLED_PRODUCT_NAME="\"Custom Product\""
