[Apex 5.1]
Hi everyone,
I had a default created application. I'm trying, to change it little bit.
First I made the Home page public and in order to access private content, the user has to click Log In in the Navigation Bar, then he will be redirected to the Login Page.
I'm pretty much happy with the navigation bar when the user is connected. It displays the name of the user connected.

However before the user connects, it's empty and I would like to add two buttons : Sign Up and Log In

Does anyone know please the steps to do that ?
Thank you in advance.
