Hi Chisto assuming you have the Easy Sign Up plugin installed the normal sortcode will work :
[easy_sign_up
title="Your Title Here"
fnln="1"
phone="1"
esu_label="A unique identifier for your form"
esu_class="your-class-here"]
All the attributes are optional if you don't want them just add the short code without it, e.g.: [easy_sign_up]
