+## Aesthetic Scorer
 
+Uses existing CLiP model with an additional small pretrained to calculate perceived aesthetic score of an image  
+
+Enable or disable via `Settings` -> `Aesthetic scorer`  
+
+This is an *"invisible"* extension, it runs in the background before any image save and  
+appends **`score`** as *PNG info section* and/or *EXIF comments* field
+
+### Notes
+
+- Configuration via **Settings** &rarr; **Aesthetic scorer**  
+  ![screenshot](https://raw.githubusercontent.com/vladmandic/sd-extension-aesthetic-scorer/main/aesthetic-scorer.jpg)
+- Extension obeys existing **Move VAE and CLiP to RAM** settings
+- Models will be auto-downloaded upon first usage (small)
+- Score values are `0..10`  
+- Supports both `CLiP-ViT-L/14` and `CLiP-ViT-B/16`
+- Cross-platform!
+
+## Steps Animation
+
+Extension to create animation sequence from denoised intermediate steps  
+Registers a script in **txt2img** and **img2img** tabs
+
+Creating animation has minimum impact on overall performance as it does not require separate runs  
+except adding overhead of saving each intermediate step as image plus few seconds to actually create movie file  
+
+Supports **color** and **motion** interpolation to achieve animation of desired duration from any number of interim steps  
+Resulting movie fiels are typically very small (*~1MB being average*) due to optimized codec settings
