Call out opening bracket behavior in FAQ

Apparently mentioning in the both the README intro and the help file
isn't enough.  I give up.

-Installation
-------------
+## Installation
 
-If you don't have a preferred installation method, I recommend
-installing [pathogen.vim](https://github.com/tpope/vim-pathogen), and
-then simply copy and paste:
+Install using your favorite package manager, or use Vim's built-in package
+support:
 
-    cd ~/.vim/bundle
-    git clone git://github.com/tpope/vim-surround.git
+    mkdir -p ~/.vim/pack/tpope/start
+    cd ~/.vim/pack/tpope/start
+    git clone https://tpope.io/vim/surround.git
+    vim -u NONE -c "helptags surround/doc" -c q
 
-Once help tags have been generated, you can view the manual with
-`:help surround`.
+## FAQ
 
-Contributing
-------------
+> How do I surround without adding a space?
+
+Only the opening brackets—`[`, `{`, and `(`—add a space.  Use a closing
+bracket, or the `b` (`(`) and `B` (`{`) aliases.
