Hint: Better Example for Pattern

Problem/Motivation

Thanks for good Module! For installing i need little help. Maybe the README could be updatet, that it will be better to understand.

Steps to reproduce

What is an example for search-pattern?
The Name of my field is sid. What is the name of the search-pattern i have to use in de docx template?
I tested:
${sid}
${field_sid}
${field_field_sid}
... but nothing work.

I tested it in drupal9.1.4

Secound hint for documentation:
The library of phpoffice has to be saved in "modules/doc_serialization/lib/phpoffice-phpword". After that it has to be installed by using the module Ludwig (alternative way to composer)

Thanks for help!
