 ## Modularity
 
-The project was designed to be heavily modular, such that backends are fully separated from the middle-layer which is fully separated from the frontend UI, and all components are interswappable. This is to enable extensibility and customization. For example, an extension can easily provide alternative backend generators (this project comes with several built-in, such as ComfyUI, Auto WebUI, StabilityAPI, ...) without having to edit anything else to work.
