I want to change Alt tag of Logo

Hi there I am working on e-commerce website Limelight Teamwear, I want to change my logo alt tag. Is there anyone who can help me to do so?

Be that as it may, how would you change the alt properties so it says the name of my store? ... The content from the alt trait in logo picture ought to be the one which was included under the Store Setup - > Store Profile - > Store ... I don't have a record that resembles that.
