+Wikibase Usage
+--------------
+
+Wikibase is a flexible knowledge base software that drives Wikidata.
+A sample pywikibot script for getting data from Wikibase:
+
+::
+
+    import pywikibot
+    site = pywikibot.Site('wikipedia:en')
+    repo = site.data_repository()  # the wikibase repository for given site
+    page = repo.page_from_repository('Q91')  # create a local page for the given item
+    item = pywikibot.ItemPage(repo, 'Q91')  # a repository item
+    data = item.get()  # get all item data from repository for this item
+
