get scm configuration back after accidently deletion from xcode 4

I would like to know that how do i configure my project(already checked-out) back to my previous repository? I've accidentally deleted all repositories from repositories menu from xcode4. By the way my project was previously configured with xcode 3.x开发者_C百科.

Open the Organizer window and select the Repositories tab. Click the plus button in the lower-left corner of the window. Choose Add Working Copy... from the menu. Navigate to your project's folder, select it, and click Open.

Assuming all is well with the local copy (or the repo in Git's world), Xcode will Do the Right Thing when displaying the repo status of the members of your working copy in the affected project. If it doesn't, try closing and re-opening the project.
