# Roda::Proxy
Welcome to your new gem! In this directory, you'll find the files you need to be able to package up your Ruby library into a gem. Put your Ruby code in the file `lib/roda/proxy`. To experiment with that code, run `bin/console` for an interactive prompt.
TODO: Delete this and the text above, and describe your gem
## Installation
Add this line to your application's Gemfile:
```ruby
gem 'roda-proxy'
```
And then execute:
$ bundle install
Or install it yourself as:
$ gem install roda-proxy
## Usage
TODO: Write usage instructions here
## 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 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]/roda-proxy.
## License
The gem is available as open source under the terms of the [MIT License](https://opensource.org/licenses/MIT).
