+### How to use predefined classes
+
+#### DatabaseTable, RequestMangager
+
+```cpp
+class LoginTable : public serversdk::DatabaseTable {
+    Q_OBJECT
+    TABLE_PROPERTY(QString, username, set_username, "");
+    TABLE_PROPERTY(QString, password, set_password, "")
+};
+
+serversdk::RequestManager reqMan;
+reqMan.setIgnoreSsl(true);
+
+auto loginRequest = std::make_shared<serversdk::Request>("POST", "https://192.168.1.3:8443/AaaManager/authSession", login->jsonData());
+
+// Set basic authorization
+loginRequest->setUserName(login->username());
+loginRequest->setPassword(login->password());
+
+reqMan.processRequest(loginRequest);
+
+connect(loginRequest.get(), &serversdk::Request::finished, [=](){
+    qDebug() << "Request is finished";
+});
+```
