OJS comes with a number of useful plugins by default, and more can be easily installed. You can view extra plugins at our Plugin Gallery online at http://pkp.sfu.ca/support/forum/viewforum.php?f=28.

Most plugins should come with a readme file of some sort, and should also list which versions of OJS they are compatible with. To install a plugin, you should simply need to copy the files to the correct plugins subdirectory in your OJS installation. For example, if the plugin you want to install is considered a 'generic' plugin, copy the plugin folder to plugins/generic/; if it is classed as an import plugin, it should go into plugins/importexport; and so on.

Most plugins operate at the Journal Manager level, and require no additional system configuration - that is, Journal Managers can enable and configure them once they are installed - but some plugins require additional configuration at the system level, or are only operable by Site Administrators. For more information, you should consult the plugin's documentation.
