The Duke and Duchess of Cambridge are in Ireland this week on a Royal visit to four different counties.
They begin in Dublin today, Tuesday, before heading to Meath and Kildare on Wednesday and finishing off in Galway on Thursday.
A full itinerary has been released by royal officials and road closures that are in place have been listed in full by gardai.
Other than President Michael D Higgins and a number of other high-up officials, few people will actually get to greet the royal couple.
But if you are lucky enough - these are the things you are expected to know when greeting both Prince William and Kate Middleton.
Greeting a member of the Royal family
The official royal website has a section for guidelines on how you should greet any member of the family including the Queen.
However, you are under no obligation to follow the guidelines - they state: "There are no obligatory codes of behaviour when meeting The Queen or a member of the Royal Family, but many people wish to observe the traditional forms."
But if you do wish to follow traditional forms you will have to do the following;
- For men this is a neck bow (from the head only) whilst women do a small curtsy. Other people prefer simply to shake hands in the usual way.
- On presentation to The Queen, the correct formal address is 'Your Majesty' and subsequently 'Ma'am,' pronounced with a short 'a,' as in 'jam'.
- For male members of the Royal Family the same rules apply, with the title used in the first instance being 'Your Royal Highness' and subsequently 'Sir'.
- For other female members of the Royal Family the first address is conventionally 'Your Royal Highness' and subsequently 'Ma'am'.
