Mercury fulltext problem

Hello
I am trying to add a mercury parser to the ttrss.
I already see inthe plugin the mercury fulltext. BUT I understand that I need to add a self-hosted Mercury Parser API Endpoint. Do you know and can explain me how can I add an API endpoint to the tt-rss?
Thanks

If you look at the github repo for that plugin:

To host such an API, please visit postlight/mercury-parser-api. For a dockerized self-host solution, please visit my repo HenryQW/mercury-parser-api.

Looks like you will probably need to use the docker container as the first link refers to AWS
