Here is a simple example of how to create a roll-up summary that counts how many contacts exist for a given account and keeps this number up-to-date as you add/edit contacts that are related to this account.

Create a new Account field

Starting with the Account object (where we want our counter), we create a new number field (with 0 decimal places) called Contacts Count (Contacts Count__c).

Add a Decision element

Now, we can add a decision to see if the AccountId has been changed. The Yes condition is for an existing contact record where the related Account (Account ID) has been changed.

Add a Get Records element (for Prior accounts)

Here, we want to get any contact records where the Account Id was changed on the contact. We need to update this account contact because the record may no longer be related to the account and the count needs to be recalculated.
