    Currently supported implementations are Guile and PLT.

 * Installation
 
   - In your .emacs:
 
      (load-file "<path-to-geiser>/elisp/geiser.el")
-     (geiser-setup)
 
     This installs all supported Scheme implementations. You can list
-    explicitly the ones that you want, e.g.:
+    explicitly the ones that you want by setting the variable
+    `geiser-impl-installed-implementations' *before* loading geiser.el.
+    For instance:
 
-      (geiser-setup 'plt 'guile)
+     (setq geiser-impl-installed-implementations '(plt guile))
 
     On opening a scheme file, Geiser will try to guess its Scheme,
     defaulting to the first in the list.
