 Configure an IDE
 ================
+We assume you've already `cloned <https://github.com/godotengine/godot>`_ and `compiled <_compiling.rst>`_ Godot.
+
+Kdevelop
+--------
+Is a free, open source IDE (Integrated Development Environment) for Linux, Solaris, FreeBSD, Mac OS X and other Unix flavors.
+
+You can find a video tutorial `here <https://www.youtube.com/watch?v=yNVoWQi9TJA>`_. or you may follow this text version tutorial.
+
+Okay so start by openning Kdevelop and choosing open project.
+
+.. image:: /img/kdevelop_newproject.png
+
+Choose the directory where you cloned Godot.
+
+.. image:: /img/kdevelop_openproject.png
+
+For the build system, choose custom build system.
+
+.. image:: /img/kdevelop_custombuild.png
+
+Now that the project has been imported, open the project configuration.
+
+.. image:: /img/kdevelop_openconfig.png
+
+Add the following includes/imports:
+
+* . (a dot to indicate the root of the Godot project)
+* core/
+* core/os/
+* core/math/
+* tools/
+* drivers/
+* platform/x11/ (Make that platform/osx/ is you're using OS X)
+
+.. image:: /img/kdevelop_addincludes.png
+
+Apply the changes then switch to the Custom Buildsystem tab. Leave the build directory blank. Enable build tools and add 'scons' as the executable and add 'platform=x11 target=debug' ('platform=osx' if you're on OS X)
+
+.. image:: /img/kdevelop_buildconfig.png
+
+Next we need to tell kdevelop where to find the binary. so from the run menu choose Configure Launches.
+
+.. image:: /img/kdevelop_configlaunches.png
+
+Add new if you none exists. And then add the path to your executable in the executable section. Your executable should be located in the bin/ sub-directory and should be named something like: 'godot.x11.tools.64' (the name could be different depending on your platform and depending on your build options).
+
+.. image:: /img/kdevelop_configlaunches2.png
+
+That's it! Now you should be good to go :)
