+
+RDP server for
+[org.qemu.Display1](https://www.qemu.org/docs/master/interop/dbus-display.html)
+interface (as exposed by `qemu -display dbus`).
+
+The project was originally designed to work with QEMU, but it can be used with
+other displays/UI that implement the D-Bus interface.
+
+## Features
+
+- RDP server in Rust thanks to IronRDP
+- using TLS/CredSSP for secure connections
+- text clipboard sharing
+- audio playback
+- monitor resize
+- remotefx image codec
+- Opus audio codec (works with some clients, like FreeRDP)
+
+## Installation & usage
+
+```
+cargo install qemu-rdp
+```
+
+To run the server against qemu, the simplest way is to use `qemu -display dbus` and
+run the server: (requires certificate and key)
+```bash
+qemu-rdp serve --bind-address YOUR_IP:3389 --cert=CERT.PEM --key=KEY.PEM
+```
+
+Although for a complete setup (with audio devices, clipboard and such), you may
+want to wait for libvirt to support it.
+
+## TODO
+
+Some ideas to improve the project:
+
+- [ ] some video/image codec (AV1/AVC/HEVC)
+- [ ] USB redirection
+- [ ] audio recording
+- [ ] more types clipboard redirection
+- [ ] file system redirection
+- [ ] multimonitor
+- tons of other stuff from RDP features, and a lot of bug fixes🐛
