+Getting the source
+==================
+
+Downloading the Godot source code
+---------------------------------
+
+Before :ref:`getting into the SCons build system <doc_introduction_to_the_buildsystem>`
+and compiling Godot, you need to actually download the Godot source code.
+
+The source code is available on `GitHub <https://github.com/godotengine/godot>`__
+and while you can manually download it via the website, in general you want to
+do it via the ``git`` version control system.
+
+If you don't know much about ``git`` yet, there are a great number of
+`tutorials <https://git-scm.com/book>`__ available on various websites.
+
+In general, you need to install ``git`` and/or one of the various GUI clients.
+
+Afterwards, to get the latest development version of the Godot source code
+(the unstable ``master`` branch), you can use ``git clone``.
+
+If you are using the ``git`` command line client, this is done by entering
+the following in a terminal:
+
+::
+
+    git clone https://github.com/godotengine/godot.git
+
+For any stable release, visit the `release page <https://github.com/godotengine/godot/releases>`__
+and click on the link for the release you want.
+You can then download and extract the source from the download link on the page.
+
+There are also generally branches besides ``master`` for each major version.
+
+After downloading the Godot source code,
+you can :ref:`continue to compiling Godot <doc_introduction_to_the_buildsystem>`.
