-A single-file Vim plugin manager.

-Somewhere between [Pathogen](https://github.com/tpope/vim-pathogen) and

 ### Pros.
 
-- Easier to setup
-- Parallel installation/update (requires
-  [+ruby](http://junegunn.kr/2013/09/installing-vim-with-ruby-support/))
-- Smallest possible feature set
-- Branch/tag support
-- On-demand loading
-
-### Cons.
-
-- Everything else
+- Easier to setup: Single file. No boilerplate code required.
+- Easier to use: Concise, intuitive syntax
+- [Super-fast](https://raw.github.com/junegunn/i/master/vim-plug/40-in-4.gif)
+  parallel installation/update (requires
+  [+ruby](https://github.com/junegunn/vim-plug/wiki/ruby))
+- On-demand loading to achieve
+  [fast startup time](http://junegunn.kr/images/vim-startup-time.png)
+- Post-update hooks
+- Can choose a specific branch or tag for each plugin
+- Support for externally managed plugins

-### FAQ/Troubleshooting
-
-#### Plugins are not installed/updated in parallel
-
-Your Vim does not support Ruby interface. `:echo has('ruby')` should print 1.
-In order to setup Vim with Ruby support, you may refer to [this
-article](http://junegunn.kr/2013/09/installing-vim-with-ruby-support).
-
-#### *Vim: Caught deadly signal SEGV*
-
-If your Vim crashes with the above message, first check if its Ruby interface is
-working correctly with the following command:
-
-```vim
-:ruby puts RUBY_VERSION
-```
-
-If Vim crashes even with this command, it is likely that Ruby interface is
-broken, and you have to rebuild Vim with a working version of Ruby.
-(`brew remove vim && brew install vim` or `./configure && make ...`)
-
-If you're on OS X, one possibility is that you had installed Vim with
-[Homebrew](http://brew.sh/) while using a Ruby installed with
-[RVM](http://rvm.io/) or [rbenv](https://github.com/sstephenson/rbenv) and later
-removed that version of Ruby.
-
-[Please let me know](https://github.com/junegunn/vim-plug/issues) if you can't
-resolve the problem. In the meantime, you can set `g:plug_threads` to 1, so that
-Ruby installer is not used at all.
-
-#### Errors on fish shell
-
-If vim-plug doesn't work correctly on fish shell, you might need to add `set
-shell=/bin/sh` to your .vimrc.
-
-Refer to the following links for the details:
-- http://badsimplicity.com/vim-fish-e484-cant-open-file-tmpvrdnvqe0-error/
-- https://github.com/junegunn/vim-plug/issues/12
-
-#### Freezing plugin version with commit hash
-
-vim-plug does not allow you to freeze the version of a plugin with its commit
-hash. This is by design. I don't believe a user of a plugin should be looking
-at its individual commits. Instead, one should be choosing the right version
-using release tags or versioned branches (e.g. 1.2.3, stable, devel, etc.)
-
-```vim
-Plug 'junegunn/vim-easy-align', '2.9.2'
-```
-
-If the repository doesn't come with such tags or branches, you should think of
-it as "unstable" or "in development", and always use its latest revision.
-
-If you really must choose a certain untagged revision, consider forking the
-repository.
-
-#### Migrating from other plugin managers
-
-vim-plug does not require any extra statement other than `plug#begin()` and
-`plug#end()`. You can remove `filetype off`, `filetype plugin indent on` and
-`syntax on` from your .vimrc as they are automatically handled by
-`plug#end()`.
