## How can I delete all contacts?
1. In the left menu (in sidebar) go to `Address book->All contacts`
2. Click `Delete all contacts` button. Depending on the viewport, it may be hidden under the `More actions` button (the symbol of three dots above each other)
3. Check the box `I'm sure, what I'm doing`
4. Click the `Delete` button
5. All your contacts will be permanently removed from the address book (and all groups)
