 # Stable Diffusion web UI
 A browser interface based on Gradio library for Stable Diffusion.

 Gradio's loading graphic has a very negative effect on the processing speed of the neural network.

+### Textual Inversion
+Allows you to use pretrained textual inversion embeddings.
+See originial site for details: https://textual-inversion.github.io/.
+I used lstein's repo for training embdedding: https://github.com/lstein/stable-diffusion; if
+you want to train your own, I recommend following the guide on his site.
+
+No additional libraries/repositories are required to use pretrained embeddings.
+
+To make use of pretrained embeddings, create `embeddings` directory in the root dir of Stable
+Diffusion and put your embeddings into it. They must be .pt files about 5Kb in size, each with only
+one trained embedding, and the filename (without .pt) will be the term you'd use in prompt
+to get that embedding.
+
+As an example, I trained one for about 5000 steps: https://files.catbox.moe/e2ui6r.pt; it does
+not produce very good results, but it does work. Download and rename it to `Usada Pekora.pt`,
+and put it into `embeddings` dir and use Usada Pekora in prompt.

+
+### Settings
+A tab with settings, allowing you to use UI to edit more than half of parameters that previously
+were commandline. Settings are saved to config.js file. Settings that remain as commandline
+options are ones that are required at startup.
