 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.
+
+ This may not work with certain browser configurations — especially mobile browsers.
  * 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
