For more information on using SVN, refer to the official WordPress SVN Documentation.

Steps to Upload Plugin via SVN:

cp yourplugin.php my-local-dir/trunk/
cp style.css my-local-dir/trunk/

cp screenshot-1.png my-local-dir/assets/
cp icon-128x128.png my-local-dir/assets/
cp icon-256x256.png my-local-dir/assets/

3. Add and commit your files to the SVN repository:

cd my-local-dir/yourplugin-dir-name
svn add trunk/*
