+<h3>What are cookies?</h3>
+<p>Cookies are small text files placed on your browser by websites. They help make websites work, or work more efficiently. They also "remember" some of your preferences, so you don't have to set a preference again every time you switch to a different page on the same website.</p>
+<p>If cookies are a concern for you, you may like to regularly clear your cookies on your browser or use a private browser mode. Check your browser settings for these options.</p>
+<h3>Essential cookies</h3>
+<p>Here is the list of essential cookies used on the Koha online catalog.</p>
+<p>Some of these depend on settings chosen by the library team; therefore all the cookies listed may not apply to this site.</p>
