 ### text2img generation
 
-`text2img` can be thought of as generating visual content based on textual descriptions. Popular models include [DALL-E](https://openai.com/dall-e-2), [Midjourney](https://www.midjourney.com/home), and [Stable Diffusion](https://stability.ai/blog/stable-diffusion-public-release). Stable Diffusion (such as SD1.5 and SDXL1.0) are open and gives us the more control on the image generation process.

+Prompt:
+```cute cat, 4k ultra hd, highly detailed```
+Negative Prompt:
+```orange cat```

 ### img2img generation
 
-`img2img` refers to the transformation of one image into another, typically maintaining the same content but changing the style or other visual attributes.
+`img2img` refers to the transformation of one image into another, typically maintaining the same content but changing the style or other visual attributes. A1111 has a `img2img` tab where you can try this. You can also suppliment the generation with a text prompt.

+### Inpaint
+
+Inpainting is a technique to make small modification or fix small defects on an image. A1111 has an `inpaint` tab under the `img2img` tab.
 
 ### ControlNet (+Stable Diffusion)
 
+ControlNet is a neural network structure to control diffusion models by adding extra conditions
