Step 1: Login
Head to www.icloud.com and log in using your Apple details. Tick the box under the login options if you want to automatically be logged in every time.
Step 2: Get in contact
You will now see five icons. You can access plenty of other features here, but for now you need to click on the Contacts icon.
Step 3: Duplicates
The display will be familiar to anyone who has used the Address Book in Lion. Here we can see a duplicated contact, so let’s delete one of them.
Step 4: Erasing contacts
You can either click Edit in the bottom-left corner of the contact card and scroll to find the Delete button, or click the contact and press Backspace.
Step 5: Get a new card
Your card will have a small user icon. If your card isn’t right, select the one you want to make your card and choose Make This My Card from the Settings menu.
Step 6: Preferential
If you click on the Settings cog and choose Preferences, you can change things like the layout of addresses and the way names are displayed.
Step 7: As a group
It’s also possible to select several contacts at once. Hold the Command key and click those you want. You can either delete the lot, or create a group.
Step 8: Grouping
Click Create Group and you’ll be taken to this screen, where you can change the name of your group or delete it. This is great for the fast sorting of contacts.
