Integrate Docxmerge

We believe that developers should focus their time on things that matter, not setting up yet another rendering library. Because we eliminate needless complexity and provide an up-to-date service, you can get up and running with Docxmerge in just a couple of minutes.

// step 1, install docxmerge
// npm install docxmerge

// Step 2, import libraries
