Sending an email only when field is updated - Process builder

Hey
I have a question about the conditions for sending an email alert.
What are the Conditions That I should do when the field is updated and only then the customer receives an email.

"When "Driving License Number" field (text type) is updated in the Contact object, an Email should be sent"

THANK YOU SO MUCH

If you are using text field then try below.

Select 'Formula evaluates to true' in process builder and try below formula 
ISCHANGED([Contact].Driving License Number__c )
Thanks,

Hi Neta,

You can use process builder or workflow rule to trigger email whenever field is updated.

Check below examples.

Hey You! Thank you for you answer.
The option "equal"  - "Boolean" does not show. Maybe because the field is a text type?
So I tried to do this:
Operator: Equals
Type: is changed
Value: true

but it didn't work out :(

I tried this but when i updated the field an error message shows:

We can't save this record because the “Car Process” process failed. Give your Salesforce admin these details. We were unable to process the email template. Error Message: core.email.template.TemplateRenderingException: We don't recognize the field prefix Recipient. Associate a record that matches the prefix or update the template to remove the merge field from the body, subject, or letterhead. Error ID: 2058668558-2800 (-173753846)

This seem to issue with merge fields on email template.  Can you check?

"Dear {{{Recipient.FirstName}}}, on {{{Recipient.CreatedDate}}}, Driver's license number has been updated to the following number: {{{Recipient.Driving_License_Number__c}}}"
