	"GFPGAN": "Restore low quality faces using GFPGAN neural network",
	"Euler a": "Euler Ancestral - very creative, each can get acompletely different pictures depending on step count, setting seps tohigher than 30-40 does not help",
	"DDIM": "Denoising Diffusion Implicit Models - best at inpainting",

	"Batch count": "How many batches of images to create",
	"Batch size": "How many image to create in a single batch",
    "CFG Scale": "Classifier Free Guidance Scale - how strongly the image should conform to prompt - lower values produce more creative results",
    "Seed": "A value that determines the output of random number generator - if you create an image with same parameters and seed as another image, you'll get the same result",

    "Inpaint a part of image": "Draw a mask over an image, and the script will regenerate the masked area with content according to prompt",
    "Loopback": "Process an image, use it as an input, repeat. Batch count determings number of iterations.",

    "Inpaint at full resolution": "Upscale masked region to target resolution, do inpainting, downscale back and paste into original image",

    "Denoising Strength": "Determines how little respect the algorithm should have for image's content. At 0, nothing will change, and at 1 you'll get an unrelated image.",

    "X/Y plot": "Create a grid where images will have different parameters. Use inputs below to specify which parameterswill be shared by columns and rows",
    "Custom code": "Run python code. Advanced user only. Must run program with --allow-code for this to work",
