+Adding Cookie Consent (for GDPR, etc.)
+++++++++++++++++++++++++++++++++++++++
+
+Cookie consent may be required on websites that use analytics tracking codes to comply with privacy regulations, such as the GDPR, which mandate informing users about the collection and use of their data, thereby giving them the option to accept or reject cookies for enhanced privacy and control over their personal information.
+
+Members of the Dataverse community have used the CookieConsent (https://cookieconsent.orestbida.com) JavaScript library for this purpose. Configuration advice is below.
+
+To allow users to opt out of the use of Google Analytics tracking you can do the following:
+
+1. Assuming you already have ``analytics-code.html`` added and configured, update the Google Analytics scripts by adding  ``type``, ``data-category``, and ``data-service`` arguments like this:
+
+.. code-block:: html
+
+    <!-- Global Site Tag (gtag.js) - Google Analytics -->
+    <script
+        async="async"
+        src="https://www.googletagmanager.com/gtag/js?id=YOUR-ACCOUNT-CODE"
+        type="text/plain"
+        data-category="analytics"
+        data-service="Google Analytics"></script>
+    <script
+        type="text/plain"
+        data-category="analytics"
+        data-service="Google Analytics">
+        //<![CDATA[
+	window.dataLayer = window.dataLayer || [];
+	function gtag(){dataLayer.push(arguments);}
+	gtag('js', new Date());
+
+	gtag('config', 'YOUR-ACCOUNT-CODE');
+        //]]>
+    </script>
+
+2. Add to ``analytics-code.html``:
+
+``<link rel="stylesheet" href="https://cdn.jsdelivr.net/gh/orestbida/cookieconsent@v3.0.0/dist/cookieconsent.css">``
+
+3. Go to https://playground.cookieconsent.orestbida.com to configure, download and copy contents of ``cookieconsent-config.js`` to ``analytics-code.html``. It should look something like this:
+
+.. code-block:: html
+
+    <script type="module">
+      import 'https://cdn.jsdelivr.net/gh/orestbida/cookieconsent@v3.0.0/dist/cookieconsent.umd.js';
+
+      CookieConsent.run({
+        guiOptions: {
+          consentModal: {
+            layout: "box",
+            position: "middle center",
+            equalWeightButtons: false,
+            flipButtons: false
+          },

+        },

+                    description: "For any query in relation to my policy on cookies and your choices, please <a class=\"cc__link\" href=\"#yourdomain.com\">contact me</a>."
+                  }
+                ]
+              }
+            }
+          }
+        },
+        disablePageInteraction: true
+      });
+    </script>
+
+After restarting or reloading Dataverse the cookie consent popup should appear, looking something like this:
+
+|cookieconsent|
+
+.. |cookieconsent| image:: ./img/cookie-consent-example.png
+   :class: img-responsive
+
+If you change the cookie consent config in ``CookieConsent.run()`` and want to test you changes, you should remove the cookie called ``cc_cooke`` in your browser and reload the Dataverse page to have the popup appear again. To remove cookies use Application > Cookies in the Chrome/Edge dev tool, and Storage > Cookies in Firefox and Safari.
