+## Motivation
+
+I want to:
+
+* host a free and easy-to-use Stable Diffusion UI on ZeroGPU
+* provide the necessary tools for common workflows
+* curate useful models, adapters, and embeddings
+* prefer Diffusers over custom PyTorch
+* be fast on 8GB with no offloading
+* only support CUDA on Linux/WSL
