+# StableDiffusion 2.* in dotnet
+
+This project serves as a proof-of-concept purpose of bringing StableDiffusion model into dotnet. In the unet part, this implementation uses a traced DDPM model of v2-inference-v config with pretrained v2-1_768-ema-pruned weight. And in sampling part, this project implements a simplified version of DDIM sampler.
+
+# To run the project
+
+- firstly, download model weight by 
+
+`git lfs clone`
+
+- secondly
+
+`dotnet run`
