Allowing embeds
By default, other users have the ability to embed your Release in other websites by clicking the Share button at the bottom right of your Release.
And then clicking the Embed button and copying the code in the code window and dropping it into any website.
Your Website will appear in their site with your branding on it.
Any changes you make the contents of the Release will automatically update any place it is embedded.
Disabling embeds
If you'd like to disable others from embedding your Release, you can do so via your Template Presets.
Click the hamburger menu at the top left of the Platform and find the Template Presets tab.
Click on the name of the template you are using for your Release to edit it.
At the bottom will be a checkbox labeled Disable Embed.
Click the check box and hit save.
Republish your Release.
Any Release using this template after it's republished will no longer have Embed as an option in the share features.
