+Cohere API client for Ruby.
+
+![Tests status](https://github.com/andreibondarev/cohere-ruby/actions/workflows/ci.yml/badge.svg) [![Gem Version](https://badge.fury.io/rb/cohere-ruby.svg)](https://badge.fury.io/rb/cohere-ruby)
+
+## Installation
+
+Install the gem and add to the application's Gemfile by executing:
+
+    $ bundle add cohere-ruby
+
+If bundler is not being used to manage dependencies, install the gem by executing:
+
+    $ gem install cohere-ruby
+
+## Usage
+
+### Instantiating API client
+```ruby
+client = Cohere::Client.new(
+  api_key: ENV['COHERE_API_KEY']
+)
+```
+
+## Development
+
+After checking out the repo, run `bin/setup` to install dependencies. Then, run `rake spec` to run the tests. You can also run `bin/console` for an interactive prompt that will allow you to experiment.
+
+To install this gem onto your local machine, run `bundle exec rake install`. To release a new version, update the version number in `version.rb`, and then run `bundle exec rake release`, which will create a git tag for the version, push git commits and the created tag, and push the `.gem` file to [rubygems.org](https://rubygems.org).
