+  vim whitespace sets tab, whitespace, trailing whitespace rules to reasonable values
+---
+
+To update (replacing the current version) run `webi vim-whitespace`.
+
+## Cheat Sheet
+
+The idea that tabs should be 8 spaces wide is redonkulous.
+
+This vim-whitespace plugin sets tabs to spaces (4 wide), trim trailing
+whitespace, and makes whitespace handling consistent.
+
+### How to configure manually
+
+Create the file `~/.vim/plugins/whitespace.vim`. Add the same contents as
+<https://github.com/webinstall/webi-installers/blob/master/vim-whitespace/whitespace.vim>.
+
+That will look something like this:
+
+```vim
+" handle tabs as 4 spaces, in every direction, consintently
+set tabstop=4
+set shiftwidth=4
+set smarttab
+set expandtab
+set softtabstop=4
+
+" remove trailing whitespace on save
+autocmd BufWritePre * :%s/\s\+$//e
+```
+
+You'll then need to update `~/.vimrc` to source that plugin:
+
+```vim
+" Tabs & Whitespace: reasonable defaults from webinstall.dev/vim-whitespace
+source ~/.vim/plugins/whitespace.vim
+```
