 repository in `~/bin` so you'll nearly always have it available.

 #### What's the difference from ag.vim?
 
-Well... not a lot really.
+[ag.vim][] is a fork of this repository. As of June 2016 it is marked as
+deprecated because of [licensing issues][]. There may be a different fork that
+is maintained.
+
+Some features that we might consider backporting:
+
+ - code clean-up
+ - `:AckWindow`
+ - optional background search execution with [vim-dispatch]
+ - auto-previewing
+
+You might consider adding [the following configuration][ack mappings] to your
+`.vimrc` to get similar functionality when using ack.vim plugin:
 
-Present maintainer, yours truly, [kind of wishes they never forked][sadface],
-contributes to both, and wouldn't mind seeing them merged again. ag.vim got a
-nice code clean-up (which ack.vim is now hopefully getting), and ack.vim picked
-up a few features that haven't made their way to ag.vim, like `:AckWindow`,
-optional background search execution with [vim-dispatch], and auto-previewing.

 Most of the `:[L]Ack*` commands support this. Note that this behavior follows
 the convention of Vim's built-in `:grep` and `:make` commands.
