    Add documentation for changing the default browser
    
    Technically this isn't part of engine-mode, but it's something that
    users would conceivably want to know. Might as well explain it!

+## Changing your default browser
+
+`engine-mode` uses `browse-url` to open the URL it constructs. To
+change the browser that `browse-url` uses, you'll need to redefine
+the `browse-url-browser-function` variable.
+
+For example, to use Emacs' built-in `eww` browser:
+
+```emacs
+(setq browse-url-browser-function 'eww-browse-url)
+```
+
+The implementation of the `browse-url-browser-function` variable
+contains a comprehensive list of possible browsing functions. You can
+get to that by hitting `C-h v browser-url-browser-function <RETURN>`
+and following the link to `browse-url.el`.
