+            <p>
+              Use this page to create publications for a game system using a
+              schema, either from scratch or by extending another publication.
+              You can also create an updated version of a previous publication
+              and label it with a new release tag.
+            </p>
+            <p>
+              Each schema field that can hold a value has an input for you to
+              edit - if there are any questions about what a field is, those
+              questions should be directed to the schema author using the
+              contact feature on their profile.
+            </p>
+            <p>
+              Some fields are marked as &quot;visible.&quot; These fields are
+              the ones you can actually see when you view the publication. Some
+              of these fields will already be filled in by the schema itself so
+              that they can include specific formatting. Every schema has at
+              least one visible field - called the &quot;parent&quot; field -
+              that are shown by default when viewing the publication. Visible
+              fields appear as an option in a menu when viewing a publication.
+            </p>
+            <p>
+              Visible fields use ttcMD to create neat and tidy layouts. If you
+              don&apos;t know how to use ttcMD or ttcQuery, pleas see{" "}
