+ # OFREP Provider for OpenFeature
+
+A Rust implementation of the OpenFeature OFREP provider, enabling dynamic
+feature flag evaluation in your applications.
+
+This provider allows to connect to any feature flag management system that supports OFREP.
+
+### Installation
+Add the dependency in your `Cargo.toml`:
+```bash
+cargo add open-feature-ofrep
+cargo add open-feature
+```
+Then integrate it into your application:
+
+```rust
+use std::time::Duration;
+use open_feature::provider::FeatureProvider;
+use open_feature::EvaluationContext;
+use open_feature_ofrep::{OfrepProvider, OfrepOptions};
+use reqwest::header::{HeaderMap, HeaderValue};
+
+#[tokio::main]
+async fn main() {
+    let mut headers = HeaderMap::new();
+    headers.insert("color", HeaderValue::from_static("yellow"));
+
+    let provider = OfrepProvider::new(OfrepOptions {
+        base_url: "http://localhost:8016".to_string(),
+        headers: headers.clone(),
+        connect_timeout: Duration::from_secs(4), 
+        ..Default::default()
+    }).await.unwrap();
+
+    let context = EvaluationContext::default()
+                    .with_targeting_key("user-123")
+                    .with_custom_field("color", "yellow");
+
+    let result = provider.resolve_bool_value("isColorYellow", &context).await.unwrap();
+    println!("Flag value: {}", result.value);
+}
+```
+
