+**v0.0.3: at the moment, epidemic.vim only supports plugins in the form of git repositories.**
+
+## Requirements
+
+The `git` command must be available in the PATH.
+
+## Installation
+
+    gem install vim-epidemic
+
+## Usage
+
+Add plugin repositories with `vim-epidemic add <REPO>` (see <a href="#configuration">Configuration</a>).

+Install/update all registered plugins with `vim-epidemic update`. New plugin repositories will be cloned into `.vim/bundle`; existing ones will be updated with `git pull`.
+
+The repositories must be publicly accessible.
+
+<a name="configuration"></a>
+## Configuration
+
+epidemic.vim looks for `~/.epidemic.vim.rb` by default. This file is automatically created when you use the `add` command.
+
+### Register Plugins
+
+A plugin from a git repository can be added from the command line like this:
+
+    vim-epidemic add git://github.com/tpope/vim-rails.git
+
+For GitHub repositories, the `username/repo` part is sufficient:
+
+    vim-epidemic add tpope/vim-fugitive
+
+Or you can manually edit the configuration file:
+
+```ruby
+install "tpope/vim-fugitive"
+install "git://github.com/tpope/vim-rails.git"
+```
