+proxy plugin
+============
+
+The proxy plugin provides a couple helper functions to those of us who are
+stuck behind HTTP/HTTPS/FTP proxies that require authentication.
+
+## Usage
+
+In all cases you will need to add 'proxy' to your fish_plugins list in
+config.fish
+
+### No authentication
+
+If you just want to have the proxy plugin configure all the environment
+variables, you may set proxy_host:
+
+    set proxy_host myproxy.example.com:8000
+
+The proxy plugin will prepend `http://` for you.  Here's the result:
+
+    ~> set -x |grep proxy
+    ALL_PROXY http://myproxy.example.com:8000
+    FTP_PROXY http://myproxy.example.com:8000
+    HTTPS_PROXY http://myproxy.example.com:8000
+    HTTP_PROXY http://myproxy.example.com:8000
+    NO_PROXY http://myproxy.example.com:8000
+    all_proxy http://myproxy.example.com:8000
+    ftp_proxy http://myproxy.example.com:8000
+    http_proxy http://myproxy.example.com:8000
+    https_proxy http://myproxy.example.com:8000
+    no_proxy http://myproxy.example.com:8000
+
+### With authentication
+
+Set your proxy host and username:
+
+    set proxy_host myproxy.example.com:8000
+    set proxy_user mylogin
+
+When you need to make use of the proxy, just run `proxy`.  It will prompt you
+for a password and setup your environment.
+
+If you didn't setup a proxy_user variable, you will be prompted for a username.
+
+If you wish to clear your proxy variables, run `noproxy`.
