This is the official, [projekt.] developed system theming engine to utilize Substratum themes! When using substratum themes, always use the official client, or CI builds available from our Telegram group:!

As a reminder, any themes run on external, third-party clients will NOT be receiving any support from the team nor the themers! This includes no support on G+, XDA and Telegram!

Theme Engine Support:
- Stock Nougat (RRO): Requires root, no exposures/themes may look weird.
- Stock Oreo (OMS):
-- Rooted device will be able to use without any requirements.
-- Unrooted device will need to buy this addon, and watch the addon's video on the listing to know how to setup them!
- Stock Samsung Nougat (RRO): Will need to buy this addon and boom, full support!
- Custom Nougat (OMS): Requires a custom ROM with interfacer installed!
