+        Spyda relies on users to contribute and add websites or URLs to be
+        considered for crawling and indexing. Without this there is no way
+        to increase the number of website indexed and crawled by Spyda.
+      </p>
+      <p>
+        To add a website to Spyda's crawler for consideration, just enter the
+        website's address or URl in the box and click "Add". Spyda will then
+        start to crawl the website, index it and it will become available for
+        future search queries.
+      </p>
+      <p>
+        If you are the author or maintainer of a website that you wish <b>NOT</b>
+        to be indexed by Spyda, please contact <a href="/support">support</a>.
