Plugin list
A full list of available Redmine plugins can be found at the Plugin Directory.
More plugins (some in very early development), which are not listed at the Plugin Directory but are publicly available on GitHub can be found using a search like this.
Installing a plugin
1. Copy your plugin directory into #{RAILS_ROOT}/plugins. If you are downloading the plugin directly from GitHub, you can do so by changing into your plugin directory and issuing a command like git clone git://github.com/user_name/name_of_the_plugin.git.
2. If the plugin requires a migration, run the following command in #{RAILS_ROOT} to upgrade your database (make a db backup before).
bundle exec rake redmine:plugins:migrate RAILS_ENV=production
3. Restart Redmine
You should now be able to see the plugin list in Administration -> Plugins and configure the newly installed plugin (if the plugin requires to be configured).
Uninstalling a plugin

bundle exec rake redmine:plugins:migrate NAME=plugin_name VERSION=0 RAILS_ENV=production
2. Remove your plugin from the plugins folder: #{RAILS_ROOT}/plugins.
