From the website’s frontend, after having logged in to the CMS, navigate to the page you would like to create a component within, and click on the ‘Edit Page’ button within the administrator’s bar at the top of the screen, or add a new page through the same bar; as highlighted within the below screenshot.

This will direct you to a CMS screen, containing all information related to the page in question. Towards the bottom of this CMS page, you should spot a ‘Components’ section, which would contain configurations for any pre-existing components for the page. In the event that you have chosen to add a new page, this section will be empty, as shown below:

Clicking on the ‘Add Component’ button at the bottom-right of the section will reveal a menu containing a list of all available components within the theme. Selecting the component you would like to add from this menu will add it into the Components section, ready for any necessary configuration tweaks.
Note that if you would like to add a component in a specific order to a page within which a number of components already exist, you may hover over the component above which the new component needs to be added, and click on the ‘Add Component Above’ button outlined below, in order to better control component order.

As with the standard ‘Add Component’ button, clicking on this icon will display a list of available components to choose from.
