# Publishing slide presentations


Don't publish content that you want to keep private or content that contains private information that you don't want to share.

A document becomes a slide presentation when one or more slides are in the document. When published, only the content contained in the slide blocks is part of the presentation.

Access and settings for slide presentations are the same as published documents.

# Adding a slide presentation to your profile

Just like with documents, it's possible to add a slide presentation to your lowercase profile. This is a nice way to create a collection of documents shown on your profile when it's enabled.

# Custom URLs

The public URL can be changed to a custom identifier using the Custom Public URL input box. This URL must be unique from any other custom URLs that you have selected for your other published documents.

A valid URL contains only letters, numbers, underscores, and hyphens.

This is the same process as setting custom URLs for documents.
