functionality.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Plugins integrate into this system and can:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>add new features<\/li>\n\n\n\n<li>extend existing features<\/li>\n\n\n\n<li>modify how parts of the website behave<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">They are installed directly inside the WordPress administration panel.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_plugins_can_do\"><\/span>What plugins can do<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p

tools<\/li>\n\n\n\n<li>security features<\/li>\n\n\n\n<li>caching and performance optimization<\/li>\n\n\n\n<li>e-commerce functionality<\/li>\n\n\n\n<li>backup systems<\/li>\n\n\n\n<li>image

WordPress dashboard:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Log in to your WordPress admin panel<\/li>\n\n\n\n<li>Go to <strong>Plugins<\/strong><\/li>\n\n\n\n<li>Click <strong>Add

to build complex websites without programming knowledge.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">However, using too many plugins or poorly maintained plugins can:<\/p>\n\n\n\n<ul
