     Example usage:
 
-      env = Environment(extensions=['jinja2htmlcompress.HTMLCompress'],
-                        autoescape=True)
+      env = Environment(extensions=['jinja2htmlcompress.HTMLCompress'])
 
     How does it work?  It throws away all whitespace between HTML tags
     it can find at runtime.  It will however preserve pre, textarea, style
     and script tags because this kinda makes sense.  In order to force
-    whitespace you can use '{{ " " }}'.
+    whitespace you can use ``{{ " " }}``.
 
     Unlike filters that work at template runtime, this remotes whitespace
     at compile time and does not add an overhead in template execution.
+
+    What if you only want to selective strip stuff?
+
+      env = Environment(extensions=['jinja2htmlcompress.SelectiveHTMLCompress'])
+
+    And then mark blocks with ``{% strip %}``:
+
+      {% strip %} ... {% endstrip %}
