 # vim-outdated-plugins
-Async plugin for showing number of your outdated plugins.
 
-## What it does?
-This plugin automatically checks if any of your plugins are outdated and display a message about that.
+A [remote](https://pynvim.readthedocs.io/en/latest/usage/remote-plugins.html)
+(non-blocking) plugin for showing the number of and automatically updating
+outdated plugins managed via [vim-plug](https://github.com/junegunn/vim-plug)
 
-To use this plugin make sure you have **git** installed.
+## What does it do?
+
+This plugin provides a mechanism for displaying a message indicating whether any
+of your plugins are outdated. It can also optionally trigger an update if
+needed. It fills a gap in [vim-plug](https://github.com/junegunn/vim-plug),
+which has no mechanism for fetching updates without also installing them and
+cannot function non-disruptively in the background
 
 ## Installation
+
+Add the following line inside of the `call plug#begin()` section of your
+`init.vim`:
+
 ```vim
-Plug 'semanser/vim-outdated-plugins'
+Plug 'thisisrandy/vim-outdated-plugins'
+```
+
+and anywhere after `call plug#end()`, add
+
+```vim
+" This line is required to check for outdated plugins on startup
+autocmd VimEnter * call CheckOutdatedPlugins()
 ```
 
 ## Configuration
+
 ```vim
 " Do not show any message if all plugins are up to date. 0 by default
 let g:outdated_plugins_silent_mode = 1
+
+" Trigger :PlugUpdate as needed. 0 by default. Note that, when triggered, this
+" will open and focus a vertical split and do blocking work, which some users may
+" find disruptive on startup
+let g:outdated_plugins_trigger_mode = 1
 ```
 
+## Requirements
+
+- [neovim](https://neovim.io/)
+- [git](https://git-scm.com)
+- [vim-plug](https://github.com/junegunn/vim-plug)
+- [python](https://www.python.org/) >= 3.5
+
+## Development
+
+Fork this repository and point the `vim-plug` section of your `init.vim` to it.
+After running `:PlugInstall`, you can edit the code directly in the `vim-plug`
+directory, which is `~/.config/nvim/plugged` by default. Note that nvim must be
+restarted for changes to be reflected. For details and a more general new
+development-oriented method, see
+[nvim-example-python-plugin](https://github.com/jacobsimpson/nvim-example-python-plugin)
