+# Admin Media Replace Plugin
+
+The **Admin Media Replace** Plugin is for [Grav CMS](http://github.com/getgrav/grav). A plugin which adds the option to replace media.
+
+## Installation
+
+Installing the Admin Media Replace plugin can be done in one of two ways. The GPM (Grav Package Manager) installation method enables you to quickly and easily install the plugin with a simple terminal command, while the manual method enables you to do so via a zip file.
+
+### GPM Installation (Preferred)
+
+The simplest way to install this plugin is via the [Grav Package Manager (GPM)](http://learn.getgrav.org/advanced/grav-gpm) through your system's terminal (also called the command line). From the root of your Grav install type:
+
+ bin/gpm install admin-media-replace
+
+This will install the Admin Media Replace plugin into your `/user/plugins` directory within Grav. Its files can be found under `/your/site/grav/user/plugins/admin-media-replace`.
+
+### Manual Installation
+
+To install this plugin, just download the zip version of this repository and unzip it under `/your/site/grav/user/plugins`. Then, rename the folder to `admin-media-replace`. You can find these files on [GitHub](https://github.com) or via [GetGrav.org](http://getgrav.org/downloads/plugins#extras).
+
+You should now have all the plugin files under
+
+ /your/site/grav/user/plugins/admin-media-replace
+
+> NOTE: This plugin is a modular component for Grav which requires [Grav](http://github.com/getgrav/grav) and the [Admin](https://github.com/getgrav/grav-plugin-admin) plugin to operate.
+
+## Usage
+
+See [Official Documentation](https://www.twelvetone.tv/docs/developer-tools/grav-plugins/admin-media-replace-plugin)
