Install PlaceholderAPI:

It is necessary to install the PlaceHolderApi plugin so that the plugin can track the data of all the existing plugins, since most plugins are compatible with PlaceholderAPI.

Choosing the placeholder:

A general list of placeholders can be found here. Some plugins that work with PlaceholderAPI are not in the list, but have this information on their resource page so make sure to check there as well.
It is very important that if your placeholder requires an expansion, you have installed this expansion through the PlaceholderAPI Cloud. Make sure to use /papi reload after installing a new expansion.

Validating a placeholder:

Make sure the placeholder is correctly formatted and is not returning empty data. You can easily verify this with the command /papi parse <player> <placeholder>.

Enabling a placeholder:

You should run the following command /superstats enable <placeholder> to start tracing the statistics to the database.

Now you can display the statistics of that placeholder on any server that has superstats installed and on any web page that has access to the plugin’s database.
