+
+# FiberedMysql2
+
+FiberedMysql2 adds Fiber support to `ActiveRecord::ConnectionAdapters::EMMysql2Adapter`
+
+## Installation
+
+Add this line to your application's Gemfile:
+
+```ruby
+gem 'fibered_mysql2'
+```
+
+And then execute:
+
+    $ bundle
+
+Or install it yourself as:
+
+    $ gem install fibered_mysql2
+
+## Support
+Tested with Rails versions 4.2, 5.2, and 6.0.
+
+## Usage
+
+Behaves the same as `ActiveRecord::ConnectionAdapters::EMMysql2Adapter` but with added Fiber safety while leasing/expiring connections.
+```ruby
+connection = FiberedMysql2::FiberedMysql2Adapter.new(client, logger, options, config)
+connection.lease
+connection.expire # Rails 5+ only
+```
+
+## 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).
