Here is a tiny Subversion (svn) HOWTO. It assumes that you've already created a repository.
To put your content into the repository:
Suppose your content (on your local computer) is in /home/abcd and the repository directory is abcdsvn:
cd /home svn import abcd http://www.sjbaker.org/abcdsvn -m "Initial import"
Checking out the entire repository
cd /home svn checkout http://www.sjbaker.org/abcdsvn
That created '/home/abcdsvn' - so you'll probably want to say:
ln -s abcdsvn abcd
...so you can pretend it's under /home/abcd
To get subsequent changes from Subversion, just go to whatever directory you want to update into and...
cd /home/abcd/efg/hij svn update
Subversion remembers all of the other information in the '.svn' directory - so no more messy parameters you to worry about!
Changing your local version
svn add foo
Schedule the addition of 'foo' (and everything beneath it if it's a directory).
svn delete foo
Schedule 'foo' to be deleted from the repository - also deletes the local copy. If it's a directory, everything beneath it goes too.
svn copy foo bar svn move foo bar
Schedule 'foo' to be moved or copied into 'bar'.
svn commit --message "reason for committing"
This updates everything
