           There should be an equal number of <Tab/> and <TabPanel/> components.
           <Tab/> and <TabPanel/> components are tied together by the order in
           which they appear. The first (index 0) <Tab/> will be associated with
-          the <TabPanel/> of the same index. Running this example when
-          `selectedIndex` is 0 the tab with the label "Foo" will be selected
+          the <TabPanel/> of the same index. When you run this example with
+          `selectedIndex` equal to 0, the tab with the label "Foo" will be selected
           and the content shown will be "Hello from Foo".
 
           As with <Tab/> the content of <TabPanel/> will be shown as the content.
