+## Features
+The script creates a web UI for Stable Diffusion's txt2img and img2img scripts. Following are features added
+that are not in original script.
+
+### GFPGAN
+Lets you improve faces in pictures using the GFPGAN model. There is a checkbox in every tab to use GFPGAN at 100%, and
+also a separate tab that just allows you to use GFPGAN on any picture, with a slider that controls how strongthe effect is.
+
+![](images/GFPGAN.png)
+
+### Sampling method selection
+Pick out of three sampling methods for txt2img: DDIM, PLMS, k-diffusion:
+
+![](images/sampling.png)
+
+### Prompt matrix
+Separate multiple prompts using the `|` character, and the system will produce an image for every combination of them.
+For example, if you use `a house in a field of grass|at dawn|illustration` prompt, there are four combinations possible (first part of prompt is always kept):
+
+- `a house in a field of grass`
+- `a house in a field of grass, at dawn`
+- `a house in a field of grass, illustration`
+- `a house in a field of grass, at dawn, illustration`
+
+Four images will be produced, in this order, all with same seed and each with corresponding prompt:
+
+![](images/prompt-matrix.png)
+
+### Flagging
+Click the Flag button under the output section, and generated images will be saved to `log/images` directory, and generation parameters
+will be appended to a csv file `log/log.csv` in the `/sd` directory.
+
+### Copy-paste generation parameters
+A text output provides generation parameters in an easy to copy-paste form for easy sharing.
+
+![](images/kopipe.png)
+
+### Correct seeds for batches
+If you use a seed of 1000 to generate two batches of two images each, four generated images will have seeds: `1000, 1001, 1002, 1003`.
+Previous versions of the UI would produce `1000, x, 1001, x`, where x is an iamge that can't be generated by any seed.
