Where to enter shortcode for up- and downgrade (Missing Manual)

Hi Guys,

obviously this [ms-membership-signup] short code is the one to use to change membership level.

However but WHERE can I enter the text to describe the various membership levels?

Tried to create a new page, named enrollment option. Placed in that the short code for RENEW a membership by using the following


but it didn’t work out. Also wondering, which text is to choose as it is already named renew?

Please can you advise how to do it correctly?

Thank you
