+    <summary>A Beautiful Gemini Client</summary>
+    <description>
+        <p>
+            Lagrange is a desktop GUI client for browsing Geminispace. 
+            It offers modern conveniences familiar from web browsers, 
+            such as smooth scrolling, inline image viewing, multiple 
+            tabs, visual themes, Unicode fonts, bookmarks, history, and
+            page outlines.
+        </p>
+        <p>
+            Like the Gemini protocol, Lagrange has been designed with
+            minimalism in mind. It depends on a small number of essential
+            libraries. It is written in C and uses SDL for 
+            hardware-accelerated graphics. OpenSSL is used for secure
+            communications.
