+  vim mouse is Vim's built-in mouse support
+---
+
+To update (replacing the current version) run `webi vim-mouse`.
+
+## Cheat Sheet
+
+Vim has built-in mouse support.
+
+It is turned off by default and when turned on may not behave exactly as
+expected.
+
+This vim-mouse plugin turns on mouse support with insert mode on click,
+select-to-copy clipboard, and other GUI options.
+
+### How to configure manually
+
+Create the file `~/.vim/plugins/mouse.vim`. Add the same contents as
+<https://github.com/webinstall/webi-installers/blob/master/vim-mouse/mouse.vim>.
+
+That will look something like this:
+
+```vim
+" turn on mouse support
+set mouse=a
+
+" keep copy-on-select and other GUI options
+set clipboard+=autoselect guioptions+=a
+
+" enter insert mode on left-click
+nnoremap <LeftMouse> <LeftMouse>i
+```
+
+You'll then need to update `~/.vimrc` to source that plugin:
+
+```vim
+" Mouse Support: reasonable defaults from webinstall.dev/vim-mouse
+source ~/.vim/plugins/mouse.vim
+```
