 Integration
 -----------
+The package contains an installation script called 'sdn-install' which will bind
+'sdn' to M-o in your shell's initialisation file.  The supported shells are:
 
-zsh
-~~~
-To start using this navigator, put the following in your '.zshrc':
-
-----
-sdn-navigate () {
-  # ... possibly zle-line-finish
-  while eval "`sdn "$BUFFER" "$CURSOR"`"; do
-    [ -z "$cd" ] || cd "$cd"
-    [ -z "$insert" ] || LBUFFER="$LBUFFER$insert "
-    [ -z "$helper" ] && break
-
-    # Workaround for "zsh: suspended (tty output)" when invoking
-    # helpers after the terminal has been resized while running sdn
-    command true
-
-    /bin/sh -c "$helper" </dev/tty || break
-  done
-  # ... possibly zle-line-init
-  zle reset-prompt
-}

-bash

-Here we can't make the shell update the prompt on directory changes since
-there's no way to invoke `prompt_again()` from a `bind -x` handler but we can
-work around it by submitting a blank line:

-sdn-cursor () {
-  if [[ $BASH_VERSINFO -lt 5 ]]

-This shell is absolutely perverse.  And so is integrating 'sdn' into it because
-it already includes a custom file manager, bound to Ctrl-N (though I find
-the ranger-like interface confusing and resource-demanding).  Version 0.14.1 or
-newer is required.
+ - *zsh*: works well
+ - *bash*: minor issue: exiting the navigator confirms an empty prompt
+ - *fish*: works well
+ - *elvish*: version 0.14.1 and above, an unstable API is used, works well
