+### Custom Requests - Passing Metadata To Callbacks
+
+You can create custom requests with ```client.NewRequest```
+
+Use that request on ```geziyor.Do(request, callback)``` 
+
+```go
+geziyor.NewGeziyor(&geziyor.Options{
+    StartRequestsFunc: func(g *geziyor.Geziyor) {
+        req, _ := client.NewRequest("GET", "https://httpbin.org/anything", nil)
+        req.Meta["key"] = "value"
+        g.Do(req, g.Opt.ParseFunc)
+    },
+    ParseFunc: func(g *geziyor.Geziyor, r *client.Response) {
+        fmt.Println("This is our data from request: ", r.Request.Meta["key"])
+    },
+}).Start()
+```
