Configuring Subversion Repository Location
Subversion repository locations are global WebStorm properties. It means that the configured repository locations will be available no matter if a project is open or not, which is useful if you need to check out an entire project from Subversion. You can define multiple Subversion repository locations for future use.
To configure a Subversion repository location, do the following:
Open the SVN Repositories tool window by choosing VCS | Browse VCS Repository | Browse Subversion Repository from the main menu.
In the SVN Repositories tool window choose New | Repository Location from the context menu, or click the button on the toolbar.
In the New Repository Location dialog, specify the repository URL.
