 Gists provide a simple way to share code snippets with others. Every gist is a Git repository, which means that it can be forked and cloned. If you are signed in to {% data variables.product.product_name %} when you create a gist, the gist will be associated with your account and you will see it in your list of gists when you navigate to your {% data variables.gists.gist_homepage %}.
 
-Gists can be public or secret. public gists show up in {% data variables.gists.discover_url %}, where people can browse new gists as they're created. They're also searchable, so you can use them if you'd like other people to find and see your work.

 Secret gists don't show up in {% data variables.gists.discover_url %} and are not searchable unless you are logged in and are the author of the secret gist. Secret gists aren't private. If you send the URL of a secret gist to a friend, they'll be able to see it. However, if someone you don't know discovers the URL, they'll also be able to see your gist. If you need to keep your code away from prying eyes, you may want to [create a private repository](/repositories/creating-and-managing-repositories/creating-a-new-repository) instead.
