It looks as though the Embuary skin is hardcoded to look for "Embycon" when it's gathering data for the home screen menu and widgets. We'll need to add some docs for populating the home screen from Jellycon so we can replicate the same behavior.

From a comment on reddit we can use as a base:

To add libraries across the top under "My media"

1. Settings
2. Home and hubs
3. Edit Menu Configuration
4. Select the + symbol on an existing entry
5. Move to your new entry and select the edit symbol (box and pencil)
6. Add-On -> Video Add-On -> JellyCon -> Global Lists -> Movies -> Movies - Show All -> Create menu item to here
7. Repeat for any libraries you want linked on top.

To add widgets:

1. Settings
2. Custom widgets
3. Edit path of an entry
4. Add-On -> Video Add-On -> JellyCon -> Global Lists -> Movies -> Movies - Recently Added (20) -> Use as widget
5. Go to "Home and hubs"
6. Edit Widget Configuration
7. Select the Edit icon of an entry
8. Select your custom node from the bottom of the list
