+## Usage
+
+Images:
+
+```bash
+magick input.png src/noise_2/mocha.png -hald-clut output.png
+```
+
+Videos:
+
+```bash
+ffmpeg -i input.mkv -i src/noise_2/mocha.png -filter_complex '[0][1] haldclut' output.mp4
+```
+
+### Example script
+
+`apply.sh` is an example script that uses the LUTs provided in `src` to theme an image with each of the flavors. Multiple images and flavors at a time are supported.
+
+```bash
+bash examples/apply.sh -i examples/simon-berger-unsplash.png [-n noise] [-f flavors]
+```
+
+### (Re)generating LUTs
+
+Requirements: [cargo-play](https://crates.io/crates/cargo-play), [imagemagick](https://imagemagick.org)
+
+```bash
+# Clone the repo
+git clone https://github.com/catppuccin/palette
+cd palette 
+
+# Install deps
+yarn install # or npm i
+
+# Run the script
+node src/scripts/build_luts.mjs
+```
