+# Twig Image64 Plugin
+
+**This README.md file should be modified to describe the features, installation, configuration, and general usage of this plugin.**
+
+The **Twig Image64** Plugin is for [Grav CMS](http://github.com/getgrav/grav). Base 64 encode image
+
+## Installation
+
+Installing the Twig Image64 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 twig-image64
+
+This will install the Twig Image64 plugin into your `/user/plugins` directory within Grav. Its files can be found under `/your/site/grav/user/plugins/twig-image64`.
+
+### 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 `twig-image64`. You can find these files on [GitHub](https://github.com/paulmassen/grav-plugin-twig-image64) or via [GetGrav.org](http://getgrav.org/downloads/plugins#extras).
+
+You should now have all the plugin files under
+
+    /your/site/grav/user/plugins/twig-image64
+
+> NOTE: This plugin is a modular component for Grav which requires [Grav](http://github.com/getgrav/grav) and the [Error](https://github.com/getgrav/grav-plugin-error) and [Problems](https://github.com/getgrav/grav-plugin-problems) to operate.
+
+## Configuration
+
+Before configuring this plugin, you should copy the `user/plugins/twig-image64/twig-image64.yaml` to `user/config/plugins/twig-image64.yaml` and only edit that copy.
+
+Here is the default configuration and an explanation of available options:
+
+```yaml
+enabled: true
+```
+
+## Usage
+
+**Describe how to use the plugin.**
+
+## Credits

+**Did you incorporate third-party code? Want to thank somebody?**
