Sentinel 2 ndvi calculate in snap

I downloaded sentinel-2 data from Google earth engine.
And I corrected L1C data to L2A data using sen2cor.
I calculated ndvi raster images in Thematic Land Processing in Vegetation radiometric indices in NDVI Processor.
Do other people calculate ndvi rate like this?
When I publish my paper, I have to explain how to calculate ndvi rate.

Do I have more work to do?

I guess you will have to review some references to properly cite what is NDVI and other VI in your paper.
