+GNS3 GUI repository.
+
+Installation
+------------
+
+Please see <https://docs.gns3.com/>
+
+Software dependencies
+---------------------
+
+PyQt6 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>

-GNS3 GUI repository.
-
-Linux (Debian based)
---------------------
-
-The following instructions have been tested with Ubuntu and Mint.
-You must be connected to the Internet in order to install the dependencies.
-
-Dependencies:
-
-- Python 3.3 or above
-- Setuptools
-- PyQt 5 libraries
-- Apache Libcloud library
-- Requests library
-- Paramiko library
-
-The following commands will install some of these dependencies:
-
-.. code:: bash
-
-   sudo apt-get install python3-setuptools
-   sudo apt-get install python3-pyqt5
-   sudo apt-get install python3-pyqt5.qtsvg
-   sudo apt-get install python3-pyqt5.qtwebkit
-
-If you want to test using PyQt4
-
-.. code:: bash
-   sudo apt-get install python3-pyqt4
-
-Finally these commands will install the GUI as well as the rest of the dependencies:
-
-.. code:: bash
-
-   cd gns3-gui-master
-   sudo python3 setup.py install
-   gns3
-
-Windows
--------
-
-Please use our `all-in-one installer <https://gns3.com/software/download>`_ to install the stable build.
-
-If you install via source you need to first install:
-
-- Python (3.3 or above) - https://www.python.org/downloads/windows/
-- Pywin32 - https://sourceforge.net/projects/pywin32/
-- Qt5 - http://www.qt.io/download-open-source/
-- PyQt5 - http://www.riverbankcomputing.com/software/pyqt/download5
-- PyCrypto (which if you compile from source, requires Visual Studio 2010 with GMP or MPIR libraries)
-
-And finally, call
-
-.. code:: bash
-
-   python setup.py install
-
-to install the remaining dependencies.
-
-Mac OS X
---------
-
-Please use our DMG package or you can manually install using the following steps (experimental):
-
-`First install homebrew <http://brew.sh/>`_.
-
-Then install the GNS3 dependencies.
-
-.. code:: bash
-
-   brew install python3
-   brew install qt
-   brew install sip --without-python --with-python3
-   brew install pyqt5 --without-python --with-python3
-
-If you want to test using PyQt4
-
-.. code:: bash
-   brew install pyqt --without-python --with-python3
-
-Finally, install both the GUI & server from the source.
-
-.. code:: bash
-
-   cd gns3-gui-master
-   python3 setup.py install
-
-.. code:: bash
-
-   cd gns3-server-master
-   python3 setup.py install
-
-Or follow this `HOWTO that uses MacPorts <http://binarynature.blogspot.ca/2014/05/install-gns3-early-release-on-mac-os-x.html>`_.
