+# Remmina 远程连接
+
+Remmina is a remote desktop client written in GTK from the FreeRDP project. It supports the following protocols: SSH, VNC, RDP, NX and XDMCP.
+
+## Installation
+
+Install the remmina package.
+
+For VNC support install the libvncserver package.
+
+If you need RDP support, also install the optional freerdp or remmina-plugin-rdesktopAUR. For these note:
+
+* If the RDP option is not available in the Remmina dropdown menu after installing freerdp, make sure to completely quit Remmina first: run killall remmina. When you restart Remmina, RDP should be available.
+* As of Remmina 1.2.0, some users report RDP connections using freerdp suffer from frequent unrequested disconnections, but rdesktop RDP connections being more reliable.
+* Password saving depends on GNOME Keyring.
+
+## Usage
+
+To open previously saved connection profile you can do:
+
+```sh
+remmina -c ~/.remmina/file-name.remmina
+```
+
+Here is the script, which renames connection profile files basing on name= property to make it human readable:
+
+```sh
+#!/bin/bash
+cd ~/.remmina
+ls -1 *.remmina | while read a; do
+       N=`grep '^name=' "$a" | cut -f2 -d=`;
+       [ "$a" == "$N.remmina" ] || mv "$a" "$N".remmina;
+done
+```
+
+To minimize to tray on startup, use -i option.
