+**Brangr - *Br*owse *An*y *Gr*aph**
+
+- Brangr is a simple, unique tool that any web server can host
+  to provide a user-friendly browser/viewer for any GraphQL service (or many).
+
+- Brangr formats GraphQL results attractively, via a selection of
+  user-configurable layouts.
+  It lets users extract the generated HTML, and its source JSON.
+  It provides a clever schema browser.
+  It has built-in docs.
+
+- Brangr enables sites hosting it to present users with
+  a collection of pre-fab GraphQL requests, which they can edit if desired,
+  and let them create their own requests.
+  And it allows sites to define custom CSS styling for all aspects of the
+  formatted results.
+
+- Try it at the
+  [**public Brangr site**](https://mnmnotmail.org/bgr/brangr.html).
+
+**Example**
+
+```
+query {
+  heroes(_layout:{type:table}) { # _layout arg not sent to service
+    first
+    last
+  }
+}
+```
+
+Brangr renders the above query as follows (though not in a quote block):
+
+<blockquote>heroes...
+  <table style="border-spacing:0.5em 0">
+    <tr><th>First </th><th>Last      </th></tr>
+    <tr><td>Arthur</td><td>Dent      </td></tr>
+    <tr><td>Ford  </td><td>Prefect   </td></tr>
+    <tr><td>Zaphod</td><td>Beeblebrox</td></tr>
+  </table>
