copy the folder named George in the Packages folder of Sublime Text, located:
* on Windows: %APPDATA%\Sublime Text\Packages
* on Linux: ~/.config/sublime-text/Packages
* on macOS: ~/Library/Application Support/Sublime Text/Packages
Inside Sublime Text, go to the top bar menu and choose Preferences > Select Color Scheme…
A list of color schemes appears; select george_dark or george_light.
Open a .grg file, and its syntax will be highlighted in glorious colours.
Add these following lines in the <head> of your web page:
<script type="text/javascript" src="georgeHighlighting.js"></script>
<link rel="stylesheet" type="text/css" href="george-highlighting.css"/>
Then add an extra data attribute with the value of 'george' to the <pre> tag in which we place our code:
<pre data-lang="george">
And finally add the class which determines which theme we want, dark or light:
<pre data-lang="george" class="dark">
