+## How it works
+The project builds a proxy DLL for `paho-mqtt3as.dll` that re-exports all original functions. It hooks specific Qt network functions (`QNetworkAccessManager::createRequest`, `QWebSocket::open` and `MQTTAsync_createWithOptions`) to intercept and modify outgoing requests from the reMarkable Desktop app. The hooks redirect traffic to the configured host and port, allowing the app to communicate with a self-hosted rmfakecloud server instead of the official reMarkable cloud.
