+# Abbrev
+
+Given a set of strings, calculate the set of unambiguous abbreviations for
+those strings, and return a hash where the keys are all the possible
+abbreviations and the values are the full strings.
+
+Thus, given +words+ is "car" and "cone", the keys pointing to "car" would
+be "ca" and "car", while those pointing to "cone" would be "co", "con", and
+"cone".
+
+## Installation
+
+Add this line to your application's Gemfile:
+
+```ruby
+gem 'abbrev'
+```
+
+And then execute:

+Or install it yourself as:
+
+    $ gem install abbrev
+
+## Usage
+
+```ruby
+require 'abbrev'
+
+Abbrev.abbrev(%w{ car cone })
+#=> {"ca"=>"car", "con"=>"cone", "co"=>"cone", "car"=>"car", "cone"=>"cone"}
+```
+
+## Development

+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).
