+# Openlib
+
+This is a tiny client to the Open Library's [Books API](https://openlibrary.org/dev/docs/api/books)
+
+
+
+## Installation
+
+Add this line to your application's Gemfile:
+
+```ruby
+gem 'openlib'
+```
+
+And then execute:
+
+    $ bundle install
+
+Or install it yourself as:
+
+    $ gem install openlib
+
+## Usage
+
+```
+> book = Openlib::Book.new(id: '9780316030571')
+> book.title
+=> "Cryptonomicon"
+> book.authors
+=> ["Neal Stephenson"]
+> book.subjects
+=> ["Fiction", "World War, 1939-1945", "World War, 1939-1945 in fiction", "Data encryption (Computer science)", "Cryptography", "Literature", "Science Fiction", "Long Now Manual for Civilization", "Code and cipher stories"]
+```
+
+## Development
+
+### TODO
+
+Write some tests
+
+After checking out the repo, run `bin/setup` to install dependencies. Then, run `rake test` 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 tags, and push the `.gem` file to [rubygems.org](https://rubygems.org).
+
+## Contributing
+
+Bug reports and pull requests are welcome on GitHub at https://github.com/[USERNAME]/openlib.
+
+
+## License
+
+The gem is available as open source under the terms of the [MIT License](https://opensource.org/licenses/MIT).
