+  viminfo keeps track of Vim's state when switching between files
+---
+
+To update (replacing the current version) run `webi vim-viminfo`.
+
+## Cheat Sheet
+
+> ~/.viminfo stores cursor position, copy and paste buffers, command history,
+> and a few other goodies. The defaults aren't always good, and should be
+> tweaked.
+
+In an age where we have terabytes of storage (rather than kilobytes of storage),
+it makes sense to bump the size of Vim's copy buffers to match the full size of
+largest code file you're likely to come across, and somewhere between several
+hours and a few days worth of history.
+
+This one-line plugin does just that.
+
+### How to install manually
+
+Create the file `~/.vim/plugins/viminfo.vim`. Add the same contents as
+<https://github.com/webinstall/webi-installers/blob/master/vim-viminfo/viminfo.vim>.
+
+That will look something like this:
+
+```vim
+" Tell vim to remember certain things when we exit
+"  '100  :  marks will be remembered for up to 100 previously edited files
+"  "20000:  will save up to 20,000 lines for each register
+"  :200  :  up to 200 lines of command-line history will be remembered
+"  %     :  saves and restores the buffer list
+"  n...  :  where to save the viminfo files
+set viminfo='100,\"20000,:200,%,n~/.viminfo
+```
+
+Then `~/.vimrc` should be updated to include it:
+
+```vim
+" viminfo: reasonable defaults from webinstall.dev/vim-viminfo
+source ~/.vim/plugins/viminfo.vim
+```
