## 説明

Extends the admin role with a new, awesomer role called ‘Sysadmin’. This new role
gives you a menu of options to hide menu and/or sub-menu items in the admin from
all other users (e.g. Themes, Theme Editor, Plugin Editor, etc.) Very useful when
restricting major changes or updates from clients or administrators.

#### Special Features

 * Disable core update
 * Disable plugin update
 * Disable theme update
 * Disable admin bar

### Uninstall

Just deactivate and delete plugin. This will re-assign Sysadmin role as Administrator
and remove all options (unhiding hidden menu items, etc.)

## インストール

Activate, promote yourself, set your options, high five.

 1. Upload `system-admin` to the `/wp-content/plugins/` directory
 2. Activate the plugin through the ‘Plugins’ menu in WordPress
 3. Promote yourself to Sysadmin and visit System Admin, select your desired options,
    save changes.

## FAQ

### Is there a premium version?

No. All that this plugin does is included in this version. Nothing hidden to be 
gained.

### Does this plugin add redirects?

No. Simply hides the menu items. You can still access the direct URI (intentional
fallback).
