+## Description:
+TL;DR: Lets the bot answer you with a picture!  
+
+Stable Diffusion API pictures for TextGen, v.1.1.0  
+An extension to [oobabooga's textgen-webui](https://github.com/oobabooga/text-generation-webui) allowing you to receive pics generated by [Automatic1111's SD-WebUI API](https://github.com/AUTOMATIC1111/stable-diffusion-webui)
+
+<details>
+<summary>Interface overview</summary>
+
+![Interface](https://raw.githubusercontent.com/Brawlence/texgen-webui-SD_api_pics/main/illust/Interface.jpg)
+
+</details>
+
+Load it in the `--chat` mode with `--extension sd_api_pictures` alongside `send_pictures` (it's not really required, but completes the picture, *pun intended*).  
+
+The image generation is triggered either:  
+- manually through the 'Force the picture response' button while in `Manual` or `Immersive/Interactive` modes OR  
+- automatically in `Immersive/Interactive` mode if the words `'send|main|message|me'` are followed by `'image|pic|picture|photo|snap|snapshot|selfie|meme'` in the user's prompt  
+- always on in Picturebook/Adventure mode (if not currently suppressed by 'Suppress the picture response')  
+
+## Prerequisites
+
+One needs an available instance of Automatic1111's webui running with an `--api` flag. Ain't tested with a notebook / cloud hosted one but should be possible.   
+To run it locally in parallel on the same machine, specify custom `--listen-port` for either Auto1111's or ooba's webUIs.  
+
+## Features:
+- API detection (press enter in the API box)  
+- VRAM management (model shuffling)  
+- Three different operation modes (manual, interactive, always-on)  
+- persistent settings via settings.json
+
+The model input is modified only in the interactive mode; other two are unaffected. The output pic description is presented differently for Picture-book / Adventure mode.  
+
+Connection check (insert the Auto1111's address and press Enter):  
+![API-check](https://raw.githubusercontent.com/Brawlence/texgen-webui-SD_api_pics/main/illust/API-check.gif) 
+
+### Persistents settings
+
+Create or modify the `settings.json` in the `text-generation-webui` root directory to override the defaults
+present in script.py, ex:
+
+```json
+{
+    "sd_api_pictures-manage_VRAM": 1,
+    "sd_api_pictures-save_img": 1,
+    "sd_api_pictures-prompt_prefix": "(Masterpiece:1.1), detailed, intricate, colorful, (solo:1.1)",
+    "sd_api_pictures-sampler_name": "DPM++ 2M Karras"
+}
+```
+
+will automatically set the `Manage VRAM` & `Keep original images` checkboxes and change the texts in `Prompt Prefix` and `Sampler name` on load.
+
+---
+
+## Demonstrations:
+
+Those are examples of the version 1.0.0, but the core functionality is still the same
