+# Active Storage Colore Service
+
+[![Build Status](https://github.com/ifad/activestorage-colore/actions/workflows/ruby.yml/badge.svg)](https://github.com/ifad/activestorage-colore/actions)
+[![RuboCop](https://github.com/ifad/activestorage-colore/actions/workflows/rubocop.yml/badge.svg)](https://github.com/ifad/activestorage-colore/actions/workflows/rubocop.yml)
+
+Active Storage Colore Service is a Ruby-based client for integrating with the [Colore](https://github.com/ifad/colore) service, which provides functionalities for managing and processing color-related data in Active Storage.
+
+## Installation
+
+Add this line to your application's Gemfile:
+
+```ruby
+gem 'activestorage-colore'
+```
+
+And then execute:
+
+```sh
+bundle install
+```
+
+## Usage
+
+To use Active Storage Colore Client, you need to configure it with your Colore service endpoint and any necessary authentication details.
+
+Here is an example of how to configure and use the client:
+
+```ruby
+require 'activestorage-colore'
+
+# Configure the client
+ActiveStorage::Colore.configure do |config|
+  config.endpoint = 'https://your-colore-service-endpoint'
+  config.api_key = 'your-api-key'
+end
+
+# Example usage
+color_data = ActiveStorage::Colore.process(image_path)
+puts color_data
+```
+
+## Configuration
+
+Configuration options include:
+- `endpoint`: The URL of your Colore service endpoint.
+- `api_key`: Your API key for authenticating with the Colore service.
