+
+GNS3 GUI repository.
+
+Installation
+------------
+
+Please see <https://docs.gns3.com/>
+
+Software dependencies
+---------------------
+
+PyQt5 which is either part of the Linux distribution or installable from
+PyPi. The other Python dependencies are automatically installed during
+the GNS3 GUI installation and are listed
+[here](https://github.com/GNS3/gns3-gui/blob/master/requirements.txt)
+
+For connecting to nodes using Telnet, a Telnet client is required. On
+Linux that's a terminal emulator like xterm, gnome-terminal, konsole
+plus the telnet program. For connecting to nodes with a GUI, a VNC
+client is required, optionally a SPICE client can be used for Qemu
+nodes.
+
+For using packet captures within GNS3, Wireshark should be installed.
+It's recommended, but if you don't need that functionality you can go
+without it.
+
+Development
+-----------
+
+If you want to update the interface, modify the .ui files using QT
+tools. And:
+
+``` {.bash}
+cd scripts
+python build_pyqt.py
+```
+
+### Debug
+
+If you want to see the full logs in the internal shell you can type:
+
+``` {.bash}
+debug 2
+```
+
+Or start the app with --debug flag.
+
+Due to the fact PyQT intercept you can use a web debugger for inspecting
+stuff: <https://github.com/Kozea/wdb>
+
+Security issues
+---------------
+
+Please contact us at <security@gns3.net>
