Article: WordPress plugins alter your WordPress site beyond the default settings. They must be downloaded from the WordPress plugin directory. Most plugins can be installed automatically from the directory, but you can also install them yourself by uploading the entire folder to the /wp-content/plugins/ directory of your site. Once uploaded, activate the plugin using the Plugins menu on your WordPress site. Make sure to uncompress the file after downloading it, if your browser does not do this automatically.

If you'd like to write a blog in more than one language, a multilingual plugin can make your life much easier.

There are thousands of plugins available, so you can always search for what you're looking for. This may be useful if you are looking for a function or option that is specific to your language, such as converting one alphabet or script into another.
