Installation

As seen in a how-to on meta.discourse.org, simply add the plugin's repo url to your container's app.yml file:

hooks:
  after_code:
    - exec:
        cd: $home/plugins
        cmd:
          - mkdir -p plugins
          - git clone https://github.com/discourse/docker_manager.git
          - git clone https://github.com/fearlessfrog/steamstorewidget-onebox.git

• Rebuild the container

cd /var/discourse
git pull
./launcher rebuild app
