+# Contributing to GNS3
+
+We welcome contributions and bugs reports from everyone.
+We are friendly so don't be afraid to ask questions.
+
+## Bug reports
+
+Before reporting an issue:
+* check our website over at https://gns3.com
+* check if an issue already exists on https://github.com/GNS3/gns3-gui
+* check if an issue already exists on https://github.com/GNS3/gns3-server
+
+Please post on our community website if you are unsure you found a bug,
+you will get faster support and be able to exchange with more users.
+
+If you are unsure which project you should create an issue for, just do 
+it on https://github.com/GNS3/gns3-gui we will take care of the triage.
+
+For bugs specific to the GNS3 VM, please report on https://github.com/GNS3/gns3-vm
+
+## Security issues
+
+For security issues please keep it private and send an email to developers@gns3.net
+
+## Asking for new features
+
+The best is to start a discussion on the community website in order to get feedback
+from the whole community.
+
+
+## Contributing code
+
+We welcome code contribution from everyone including beginners.
+Don't be afraid to submit a half finished or mediocre contribution and we will help you.
+
+Don't hesitate to share your plans before starting working on a contribution, we can help
+you to find the best approach.
+
+### Contributors License Agreements
+
+We at GNS3 are eager to work with you. For small changes — little bugfixes, correcting typos, and the like — please just submit pull requests to any of our projects. For larger changes, though, we have to ask you to jump through a little hoop.
+
+In particular, in order for us to accept any major patches from you, you will have to electronically sign a statement that indicates two things:
+
+- You are willingly licensing your contributions under the terms of the open source license of the project that you’re contributing to.
+- You are legally able to license your contributions as stated.
+
+The reason we do this is to ensure, to the extent possible, that we don’t “taint” the projects we manage with contributions that turn out to be improper. This protects everyone who wants to use the projects, including you!
+
+More information there: https://github.com/GNS3/cla
+
+### Pull requests
+
+Creating a pull request is the easiest way to contribute code. Do not hesitate to create one early when  contributing for new feature in order to get our feedback.

 GNS3-gui
 ========
 
-GNS3 GUI repository (beta stage).
+.. image:: https://travis-ci.org/GNS3/gns3-gui.svg?branch=master
+    :target: https://travis-ci.org/GNS3/gns3-gui
 
-Linux (Debian based)
---------------------
+.. image:: https://img.shields.io/pypi/v/gns3-gui.svg
+    :target: https://pypi.python.org/pypi/gns3-gui
 
-The following instructions have been tested with Ubuntu and Mint.
-You must be connected to the Internet in order to install the dependencies.
 
-Dependencies:
+GNS3 GUI repository.
 
-- Python 3.3 or above
-- Setuptools
-- PyQt libraries
-- Apache Libcloud library
-- Requests library
-- Paramiko library
+Installation
+------------
 
-The following commands will install some of these dependencies:
+https://gns3.com/support/docs
+
+Development
+-------------
+
+If you want to update the interface, modify the .ui files using QT tools. And:
 
 .. code:: bash
 
-   sudo apt-get install python3-setuptools
-   sudo apt-get install python3-pyqt4
+    cd scripts
+    python build_pyqt.py
 
-Finally these commands will install the GUI as well as the rest of the dependencies:
+Debug
+"""""
+
+If you want to see the full logs in the internal shell you can type:
 
 .. code:: bash
+    
+    debug 2
 
-   cd gns3-gui-master
-   sudo python3 setup.py install
-   gns3
 
-Windows
--------
+Or start the app with --debug flag.
 
-Please use our all-in-one installer.
+Due to the fact PyQT intercept you can use a web debugger for inspecting stuff:
+https://github.com/Kozea/wdb
 
-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 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>`_.
