NOTE: This page has been migrated from the wiki to http://www.freebsd.org/doc/en_US.ISO8859-1/articles/committers-guide/subversion-primer.html - any future updates should be made there and not here.
In addition to this primer you should read http://people.freebsd.org/~peter/svn_notes.txt which documents some of the gorier and more obscure details.
You should also download http://people.freebsd.org/~peter/auto-props.txt and follow the instructions for adding the contents of that file to your ~/.subversion/config.
The "subversion book" is an excellent reference. See the first few chapters of http://svnbook.red-bean.com/.
