easiest way to setup digital signature for the staff

I am in middle of deploying Adobe DC in our company, in our old version of Adobe X staff were able to apply digital signature and I don't thing we set this up but when I upgrade adobe X to DC I cant apply digital signature and I am asked to setup the digital signature, is there a easy way of doing this? I have gone through adobe articles on setting up digital signature automatically for the staff so they don't have to create it manually but couldn't found a simple way of doing this

any help will be appreciated.
