Once you are done editing, and are through with making file changes in the local working directory, you have the option to commit the changes to the Subversion repository. You simply type the following command from the Terminal to initiate a commit.
svn commit -m "Place your comment here"
I encourage that you add comments, so you’ll know exactly what changes you’ve applied. Going forward, it will be easier to keep track of changes as you apply hundreds of commits to a project.
