Add an existing project to SVN Version

Add an existing project to SVN Version

I have downloaded Tortoise SVN. I have created SVN Repository by right
clicking on an empty folder. I have an existing project and i want to add
it to the newly created SVN Repository. So that i can checkout the project
by checkout option of SVN and do the changes and can commit it.
Copy the existing project and paste it to the SVN repository folder is not
working. Because when i use checkout option in some other folder the
copied project is not coming.
Can somebody please help , how to add an existing project to the newly
created svn repository.
