 ### Dependency resolution
 
-If a Vim plugin specifies its dependent plugins in `Plugfile` in its root

-installation.
-
-A `Plugfile` should contain a set of `Plug` commands for the dependent plugins.
-
-I've created three dummy repositories with Plugfiles as an example to this
-scheme.
-
-- [junegunn/dummy1](https://github.com/junegunn/dummy1/blob/master/Plugfile)
-  - Plugfile includes `Plug 'junegunn/dummy2'`
-- [junegunn/dummy2](https://github.com/junegunn/dummy2/blob/master/Plugfile)
-  - Plugfile includes `Plug 'junegunn/dummy3'`
-- [junegunn/dummy3](https://github.com/junegunn/dummy3/blob/master/Plugfile)
-
-If you put `Plug 'junegunn/dummy1'` in your configuration file, reload it, and
-run `:PlugInstall`,
-
-1. vim-plug first installs dummy1
-2. And sees if the repository has Plugfile
-3. Plugfile is loaded and vim-plug discovers dependent plugins
-4. Dependent plugins are then installed as well, and their Plugfiles are
-   examined and their dependencies are resolved recursively.
