Articles are what Joomla as a Content Management System was developed for. Once you installed Joomla for your website, you can start writing, editing and publishing articles right away.
Once you publish your Joomla articles, search engines start indexing them. Internet searches then find your articles in search result pages and visit your site to get more information.
Articles can be created either from Joomla backend control panel or from your site frontend. You can create them either yourself or delegate this task to somebody else.
The same applies to administering already created and published articles. They can be edited, unpublished or even deleted. Either from your site control panel or from a frontend page.
