We suggest to put the plugin in your mu-plugins directory.

There are 3 posiblities to install Clarkson Core and as with all Must Use plugins, you need to load it manually *.

Remember you still need to load Clarkson by yourself.

Quick download

Download   the latest stable .zip and place it within your mu-plugins directory.

Manual via a git clone

1. Clone the repository git clone
2. Run composer install in the new clarkson-core directory.

Install via Composer

1. Add the Git repository to your composer.json file as a independent repository

"repositories": [
    "type": "git",

2. Require it on a specific tag number

"require": {
  "composer/installers": "1.0.12",
  "johnpbloch/wordpress" : ">=4.6",
  "level-level/clarkson-core": "0.2.*"

3. Adjust to install path to install in the mu-plugins directory

"extra": {
  "installer-paths": {
    "web/app/wp-content/mu-plugins/{$name}/": ["type:wordpress-muplugin"]
  "wordpress-install-dir": "web/wp"

4. Now run composer install for your project’s Composer file.

Keep in mind that this example is based on Roots Bedrock. You could also point the mu-plugins installer-paths to something as web/wp/wp-content.
