Pair the action with the visible label

For the laundry booking screen, include the exact button name as displayed and its meaning in the reader’s language. If an automatic translation changes the button text, keep the original label alongside it. This lets the reader match the instruction to the screen. For example, if a Spanish screen displays “Reservar” and “Cancelar,” show both labels with the actions “Reserve” and “Cancel.” Someone reading an English-only instruction could otherwise press the wrong control.

Test one real task

Ask the reader to find the booking date and distinguish “reserve” from “cancel” using the guide. Let them tell you which word or step is confusing. A glossary of the whole system is less useful than accurate labels around the few actions household members actually need.

Keep translations in step

When a sign or interface changes, revise the original label and its explanation together. Mark an unsettled translation as a question for someone who understands the setting. If the action affects access or a payment, verify the meaning with the issuer before recommending a click.
