+# Continuous Desk
+
+#### More than remote desktop
+
+----
+[Chinese](README_CN.md) / [English](README.md)
+
+![example](https://github.com/dijunkun/continuous-desk/assets/29698109/f3153e28-751e-477c-b4e3-ac2384d3370f)
+
+# Intro
+
+Continuous Desk is a lightweight cross-platform remote desktop. It allows multiple users to remotely control the same computer at the same time. In addition to desktop image transmission, it also supports end-to-end voice transmission, providing collaboration capabilities on the basis of remote desktop.
+
+Continuous Desk is an experimental application of [Projectx](https://github.com/dijunkun/projectx) real-time communications library. Projectx is a lightweight cross-platform real-time communications library. It has basic capabilities such as network traversal ([RFC5245](https://datatracker.ietf.org/doc/html/rfc5245)), video softwar/hardware encoding/decoding (H264), audio encoding/decoding ([Opus](https://github.com/xiph/opus)), signaling interaction, and network congestion control ([TCP over UDP](https://libnice.freedesktop.org/)).
+
+## Usage
+
+Enter the remote desktop ID in the 'REMOTE ID' field on the menu bar, and click 'Connect' button to initiate the remote connection.
+
+![usage1](https://github.com/dijunkun/continuous-desk/assets/29698109/80099485-f2db-4f09-9fb2-e811d87265dc)
+
+If the remote desktop is set with a connection password, the local end needs to enter the correct password to initiate the remote connection. If the password is incorrect, an "Incorrect password" alert will appear in the status bar.
+
+![incorrect password](https://github.com/dijunkun/continuous-desk/assets/29698109/0b16d21a-baa6-49c1-9d87-5e80978dd345)
+
+After connection successfully established, the status bar will display the message "ClientConnected."
+
+![success](https://github.com/dijunkun/continuous-desk/assets/29698109/9c4f6604-2b1b-47b6-9c73-21c5026d1f26)
