Getting started ----------- Refer to the [SDK documentation](https://docs.launchdarkly.com/docs/ruby-sdk-reference#section-getting-started) for instructions on getting started with using the SDK. Learn more ----------- Check out our [documentation](http://docs.launchdarkly.com) for in-depth instructions on configuring and using LaunchDarkly. You can also head straight to the [reference guide for this SDK](http://docs.launchdarkly.com/docs/ruby-sdk-reference). Generated API documentation for all versions of the SDK is on [RubyDoc.info](https://www.rubydoc.info/gems/launchdarkly-server-sdk). The API documentation for the latest version is also on [GitHub Pages](https://launchdarkly.github.io/ruby-server-sdk). Testing ------- We run integration tests for all our SDKs using a centralized test harness. This approach gives us the ability to test for consistency across SDKs, as well as test networking behavior in a long-running application. These tests cover each method in the SDK, and verify that event sending, flag evaluation, stream reconnection, and other aspects of the SDK all behave correctly. Contributing ------------ We encourage pull requests and other contributions from the community. Check out our [contributing guidelines](CONTRIBUTING.md) for instructions on how to contribute to this SDK. About LaunchDarkly ----------- * LaunchDarkly is a continuous delivery platform that provides feature flags as a service and allows developers to iterate quickly and safely. We allow you to easily flag your features and manage them from the LaunchDarkly dashboard. With LaunchDarkly, you can: * Roll out a new feature to a subset of your users (like a group of users who opt-in to a beta tester group), gathering feedback and bug reports from real-world use cases. * Gradually roll out a feature to an increasing percentage of users, and track the effect that the feature has on key metrics (for instance, how likely is a user to complete a purchase if they have feature A versus feature B?). * Turn off a feature that you realize is causing performance problems in production, without needing to re-deploy, or even restart the application with a changed configuration file. * Grant access to certain features based on user attributes, like payment plan (eg: users on the ‘gold’ plan get access to more features than users in the ‘silver’ plan). Disable parts of your application to facilitate maintenance, without taking everything offline. * LaunchDarkly provides feature flag SDKs for a wide variety of languages and technologies.
