+# 🛼 skate
+A personal key-value store.
+
+![Image](./skate.png)
+
+## Usage
+Usage: `skate [command]`
+
+### KeyValues
+Set a value for a key with an optional `@` db. If `VALUE` is omitted, read value from the standard input:
+```sh
+# Usage: skate set KEY[@DB] [VALUE] [flags]
+
+skate set foo@mydb bar
+skate set foo < ./bar.txt
+```
+
+Get a value for a key with an optional `@` db:
+```shell
+# Usage: skate get KEY[@DB]
+skate get foo@mydb
+```
+
+Delete a key with an optional `@` db:
+```shell
+# Usage: skate delete KEY[@DB]
+skate delete foo@mydb
+```
+
+List key value pairs with an optional `@` db:
+```shell
+# Usage: skate list [@DB] [flags]
+
+# Options:
+#  -d, --delimiter string   delimiter to separate keys and values (default "\t")
+#  -k, --keys-only          only print keys and don't fetch values from the db
+#  -r, --reverse            list in reverse lexicographic order
+#  -b, --show-binary        print binary values
+#  -v, --values-only        only print values
+
+skate list @mydb
+```
+
+### Databases
+List databases:

+# auto-palette
+🎨 `auto-palette` is a library that automatically extracts prominent color palettes from images, available as Rust library, WebAssembly and CLI tool.
+
+## Overview
+`auto-palette` is a Rust project that offers color palette extraction from images. It consists of the following components:
+
+* `auto-palette`: Core library for programmatic usage.
+* `auto-palette-cli`: Command-line interface for easy usage.
+* `auto-palette-wasm`: WebAssembly version for browser usage.
+
+Perfect for developers, designers and anyone needing efficient color palette extraction.
+
+## Features
+* Automatically extracts prominent color palettes from images.
+* Provides detailed color swatch information (color, position, population)
+* Supports multiple extraction algorithms: `DBSCAN`, `DBSCAN++`, and `KMeans++`.
+* Supports numerous color spaces: `RGB`, `HSL`, `LAB`, `LCHuv`, `ANSI256` and more.
+* Theme-based swatch selection: `Colorful`, `Vivid`, `Muted`, `Light`, and `Dark`.
+* Available as a Rust library, Wasm, and a CLI tool.
+
+## Installation
+### Rust Library
+To use `auto-palette` in your Rust project, add it to your `Cargo.toml`.
+
+```toml
+[dependencies]
+auto-palette = "0.8.0"
+```
+
+### CLI Tool
+To use command-line interface, install the `auto-palette-cli` crate.
+
+```sh
+cargo install auto-palette-cli
+```
+
+## Usage
+### Rust Example
+Here is an example of extracting the color palette from an image using the Rust library.
+
+```rust
+use auto_palette::{ImageData, Palette};
+
+fn main() {
+  // Load the image data from the file
+  let image_data = ImageData::load("tests/assets/holly-booth-hLZWGXy5akM-unsplash.jpg").unwrap();
+
+  // Extract the color palette from the image data
+  let palette: Palette<f64> = Palette::extract(&image_data).unwrap();
+  println!("Extracted {} swatches", palette.len());
+
+  // Find the 5 dominant colors in the palette and print their information
+  let swatches = palette.find_swatches(5).unwrap();
+  for swatch in swatches {
+    println!("Color: {}", swatch.color().to_hex_string());
+    println!("Position: {:?}", swatch.position());
+    println!("Population: {}", swatch.population());
+    println!("Ratio: {}", swatch.ratio());
+  }
+}
+```
+
+### CLI Example
+Here is an example of extracting the color palette from an image using the CLI tool.
+
+```sh
+# Usage: auto-palette [OPTIONS] [PATH]
+$ auto-palette path/to/your_image.jpg -n 6 -c rgb -o table
++---+--------------------+------------+------------+
+| # | Color              | Position   | Population |
++---+--------------------+------------+------------+
+| 1 | RGB(221, 226, 222) | (104, 96)  |       6778 |
+| 2 | RGB(3, 144, 149)   | (114, 201) |       5476 |
+| 3 | RGB(23, 37, 36)    | (120, 300) |       4300 |
+| 4 | RGB(36, 88, 131)   | (183, 145) |       1348 |
+| 5 | RGB(254, 29, 44)   | (183, 190) |        779 |
+| 6 | RGB(253, 213, 116) | (25, 158)  |        567 |
