This provider is an implementation for [`go-feature-flag`](https://github.com/thomaspoignant/go-feature-flag) a simple and complete
4+
feature flag solution, without any complex backend system to install, all you need is a file as your backend.
5+
6+
It uses [`go-feature-flag-relay-proxy`](https://github.com/thomaspoignant/go-feature-flag-relay-proxy) which expose the capabilities of the SDK through an API layer.
