Creating a local Subversion repository

Version control is an important part of any code development project, to keep track of a project's history, to have full and organized backups, and to be able to easily roll back changes to get back to a known working state. Version control is also the best and most efficient way to share code and other files when developing a project in a team environment. In addition to being a great version control system that is easy to use and configure, Subversion (often referred to as SVN) is also the technology that manages all submissions on the official WordPress plugin directory. Therefore, by setting up and using a local Subversion repository during your initial plugin development, you will immediately be ready to share your creations with the community.

How to do it...

  1. Visit the TortoiseSVN website ( and download the free Subversion client for your version of Windows (32-bit or 64-bit).
