+## Setting the TLS version
+
+You can set the TLS version used during the request with the setTLSVersion method
+
+```cpp
+#include <fstream>
+#include "libcpp-http-client.hpp"
+
+using namespace lklibs;
+
+int main() {
+    HttpRequest httpRequest("https://api.myproject.com");
+    
+    // You can set the TLS version to be used for the request with setTLSVersion method
+    auto response = httpRequest
+                    .setTLSVersion(TLSVersion::TLSv1_3)
+                    .send()
+                    .get();
+    
+    return 0;
+}
+```
