General

Until recently we used Subversion as versioning control system but now have moved to Git.

Accessing the LimeSurvey Source Code

Always be aware that most of the LimeSurvey Source code is bleeding edge. Do not use it for production purposes (except fo the master branch!

As for many other free software projects only community support is available.

Access the LimeSurvey source code with a Subversion client for your operating system.

Create a GitHub account.
Download and install Git for Windows from [1]. Make sure that during install when asked for adding the Git path to your system path that you choose the "Run Git from the Windows Command Prompt" option. For further help see Set Up Git
Download and install SmartGit.
Clone the LimeSurvey repository with SmartGit. You can find the right clone URL at https://github.com/LimeSurvey/LimeSurvey .
The whole source code repository should be downloading now.
By default you should see the 'master' branch in the current directory
Use the Switch command from the SmartGit GUI to switch to the branch you need.
That's it.

Please add instructions for other OSs or complete the existing ones.
