+## Remote Evaluation Protocol
+
+The OpenFeature Remote Evaluation Protocol (OFREP) is an API specification for feature flagging that allows the use of generic providers to connect to any feature flag management systems that support the protocol.
+
+Flipt is one of the early adopters of the OFREP protocol and has implemented the protocol in its API.
+
+The OFREP protocol is still in the early stages of development, so the specification is subject to change.
+
+The API documentation for the OFREP protocol implementation in Flipt is available in the [OpenFeature Remote Evaluation](/reference/openfeature/overview) API documentation.
+
+For more information on the OFREP protocol, see the [OpenFeature Remote Evaluation Protocol](https://github.com/open-feature/protocol) repository on GitHub.
