+## Reusing fasthttp transports
+
+The Fiber client can wrap existing `fasthttp` clients so that you can reuse
+connection pools, custom dialers, or load-balancing logic that is already tuned
+for your infrastructure.
+
+### HostClient
+
+```go
+package main
+
+import (
+    "log"
+    "time"
+
+    "github.com/gofiber/fiber/v3/client"
+    "github.com/valyala/fasthttp"
+)
+
+func main() {
+    hc := &fasthttp.HostClient{
+        Addr:              "api.internal:443",
+        IsTLS:             true,
+        MaxConnDuration:   30 * time.Second,
+        MaxIdleConnDuration: 10 * time.Second,
+    }
+
+    cc := client.NewWithHostClient(hc)
+
+    resp, err := cc.Get("https://api.internal:443/status")
+    if err != nil {
+        log.Fatal(err)
+    }
+
+    log.Printf("status=%d body=%s", resp.StatusCode(), resp.Body())
+}

+### LBClient

+            &fasthttp.HostClient{Addr: "edge-2.internal:8080"},
+        },
+    }
+
+    cc := client.NewWithLBClient(lb)
+
+    // Per-request overrides such as redirects, retries, TLS, and proxy dialers
+    // are shared across every host client managed by the load balancer.
+    resp, err := cc.Get("http://service.internal/api")

 ## Cookie jar
 
 The client can store and reuse cookies between requests by attaching a cookie jar.

 The Gofiber client has been completely rebuilt. It includes numerous new features such as Cookiejar, request/response hooks, and more.
 You can take a look to [client docs](./client/rest.md) to see what's new with the client.
 
+### Fasthttp transport integration
+
+- `client.NewWithHostClient` and `client.NewWithLBClient` allow you to plug existing `fasthttp` clients directly into Fiber while keeping retries, redirects, and hook logic consistent.
+- Dialer, TLS, and proxy helpers now update every host client inside a load balancer, so complex pools inherit the same configuration.
+- The Fiber client exposes `Do`, `DoTimeout`, `DoDeadline`, and `CloseIdleConnections`, matching the surface area of the wrapped fasthttp transports.

 ## 🧰 Generic functions
 
 Fiber v3 introduces new generic functions that provide additional utility and flexibility for developers. These functions are designed to simplify common tasks and improve code readability.
