Using Subversion
If you want to help with core development, you should use subversion to get the latest source code from our Subversion repository.
On Linux systems, just install subversion in the way common to your distribution.
The following command will then fetch the latest source code from our repository:
svn co https://svn.typo3.org/TYPO3v4/Core/ typo3
Working with Subversion on Windoes is even more easy. Just use the software TortoiseSVN which can easily be used from the context menu in the Windows Explore and it helps you to easily create or apply patches to be sent to the core list or update to the latest source code from the repository. To checkout the TYPO3 source code with ToroiseSVN just right-click in any folder, chose SVN Checkout from the context menu and enter the following URL to checkout: https://svn.typo3.org/TYPO3v4/Core/
