Update README to include a link to the Turkish docs and increment the supported language count from 5 to 6. This commit adds localized guidance and references to help Turkish-speaking contributors and users.

+## Functional Options
+
+```go
+type Option func(*Server)
+
+func WithPort(port int) Option {
+    return func(s *Server) { s.port = port }
+}
+
+func NewServer(opts ...Option) *Server {
+    s := &Server{port: 8080}
+    for _, opt := range opts {
+        opt(s)
+    }
+    return s
+}
+```
+
+## Küçük Interface'ler
+
+Interface'leri implement edildikleri yerde değil, kullanıldıkları yerde tanımla.
+
+## Dependency Injection
+
+Bağımlılıkları enjekte etmek için constructor fonksiyonları kullan:
+
+```go
+func NewUserService(repo UserRepository, logger Logger) *UserService {
+    return &UserService{repo: repo, logger: logger}
+}
+```
