 Quick start
 ===========
 
 There are several quick and easy options:
 
+  * Click the ["binder" button][binder] above to open a live version of the main notebook that runs in the cloud.
+    
+    This may not work if the Binder service is too busy at the moment, and it will kill your session
+    if you don't run any commands for a few minutes.  But if it is available, this will work in any
+    modern browser.
   * Click the ["lite now" button][lite] above to open a live version of the main notebook that runs in your browser.
-  * Click the ["Binder" button][binder] above to open a live version of the main notebook that runs in the cloud.

   * Run the notebook on your own computer if you have [anaconda](https://www.anaconda.com/) installed.  Just run these commands:
     ```bash
     conda env create moble/gw_matched_filtering_demo
