    cmd/guru: update Emacs installation documentation
    
    I was going to add a hook to enable go-guru-hl-identifier-mode
    as a side effect of go-mode, but a person I consulted said that
    was bad form; instead I merely documented it.

 ;;; Commentary:
 
-;; To install the Go guru, run:
+;; To enable the Go guru in Emacs, use this command to download,
+;; build, and install the tool in $GOROOT/bin:
 ;;
-;; $ go get golang.org/x/tools/cmd/guru
+;;     $ go get golang.org/x/tools/cmd/guru
 ;;
-;; Load this file into Emacs and set go-guru-scope to your
-;; configuration.  Then, find a file of Go source code,
-;; select an expression of interest, and press `C-c C-o d' (for "describe")
-;; or run one of the other go-guru-xxx commands.
+;; Verify that the tool is on your $PATH:
+;;
+;;     $ guru -help
+;;     Go source code guru.
+;;     Usage: guru [flags] <mode> <position>
+;;     ...
+;;
+;; Then copy this file to a directory on your `load-path',
+;; and add this to your ~/.emacs:
+;;
+;;     (require 'go-guru)
+;;
+;; Inside a buffer of Go source code, select an expression of
+;; interest, and type `C-c C-o d' (for "describe") or run one of the
+;; other go-guru-xxx commands.  If you use `menu-bar-mode', these
+;; commands are available from the Guru menu.
+;;
+;; To enable identifier highlighting mode in a Go source buffer, use:
+;;
+;;     (go-guru-hl-identifier-mode)
+;;
+;; To enable it automatically in all Go source buffers,
+;; add this to your ~/.emacs:
+;;
+;;     (add-hook 'go-mode-hook #'go-guru-hl-identifier-mode)
