In this example, I will use the [{{ radarr['cf']['br-disk']['name'] }}](/Radarr/Radarr-collection-of-custom-formats/#br-disk){:target="\_blank" rel="noopener noreferrer"} Custom Format, the one most people don't want to download anyway. And if you do, then you probably don't use any of the Starr apps or Plex, being both don't support it.
Visit the [Collection of Custom Formats](/Radarr/Radarr-collection-of-custom-formats/){:target="\_blank" rel="noopener noreferrer"} and select [{{ radarr['cf']['br-disk']['name'] }}](/Radarr/Radarr-collection-of-custom-formats/#br-disk){:target="\_blank" rel="noopener noreferrer"} from the table.
Paste the `JSON` in the empty `Custom Format JSON` box (1) that you got from the [Custom Format Collection](/Radarr/Radarr-collection-of-custom-formats/){:target="\_blank" rel="noopener noreferrer"} followed by the `Import` button (2).
Check out the [How to set up Quality Profiles](/Radarr/radarr-setup-quality-profiles/) where I will explain how to make the most use of custom formats and show some personal examples that I'm using. You can use these examples to get an idea of how to set yours up.
!!! info "You can also use a [Guide sync tool](/Guide-Sync/){:target="\_blank" rel="noopener noreferrer"} to sync the Custom Formats or even the complete quality profile(s)."
