 ## Usage
 
-If you find yourself wanting to use these settings, do the following:
+If you find yourself wanting to use these settings, `git clone` this repository,
+and copy or link the following directories:
 
 ```
-./colors -> ~/.vim/colors
-./ftplugin -> ~/.vim/ftplugin
-./.vimrc -> ~/.vimrc
+colors -> ~/.vim/colors
+ftplugin -> ~/.vim/ftplugin
+plugin -> ~/.vim/plugin
 ```
 
-Also create two files `~/.vimplugin` and `~/.vimlocal`. The first one contains
-commands for your plugin manager. The idea is that you might need a different
-set of plugins on different machines. Some plugins require paths to programs,
-which can differ from machine to machine too.  
-In `.vimlocal` you should should put settings that are local to the machine.  
-You might use `plugin_template.vim` and `locals_template.vim` for reference.  
-Alternatively, if you are on UNIX and haven't configured VIM yet, you could just
-run `setup.sh`, which will do everything for you.
+In `plugin/settings.vim` are settings that you can use on every workstation.
+You can put into `~/.vimrc` settings that are local to the machine (such as
+plugins, settings for plugins, font settings, etc.). Some reasonable default
+local settings can be found in `.vimrc_template`.
+
+If you are on UNIX and haven't configured VIM yet, you could just
+run `setup.sh`, which will create links from the repository to the `~/.vim`
+folder and install plugin manager Vundle. Because of links, you shouldn't move
+or remove the directory in which you cloned this repo. The benefit is that you
+can get updates to the settings with just `git pull`.
