3 | 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/chained/rails`. To experiment with that code, run `bin/console` for an interactive prompt.
4 |
5 | TODO: Delete this and the text above, and describe your gem
6 |
7 | ## Installation
8 |
9 | Add this line to your application's Gemfile:
10 |
11 | ```ruby
12 | gem 'chained-rails'
13 | ```
14 |
15 | And then execute:
16 |
17 | $ bundle
18 |
19 | Or install it yourself as:
20 |
21 | $ gem install chained-rails
22 |
23 | ## Usage
24 |
25 | TODO: Write usage instructions here
26 |
27 | ## Development
28 |
29 | After checking out the repo, run `bin/setup` to install dependencies. You can also run `bin/console` for an interactive prompt that will allow you to experiment.
30 |
31 | 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).
32 |
