How to support custom target in MakeHuman-Js?

We are trying to develop a web app which is going to change the size of different body parts. For this we are planning to create custom targets using Make Target for Blender.
We are new to Blender and Make Human. Please let us know how can we support custom targets in MakeHuman-Js.
We tried to find some useful documentation, but we didn't get any. If you can provide link to such doc, that would be good help to us.

For this project you would need to 1) make a new makehuman target, then 2) convert it to a makehuman js target.

To 1) make a new makehuman target try searching on the makehuman forums, I'm not sure how to do that myself.

To 2) convert it to makehuman-js you use this notebook https://github.com/makehuman-js/makehuman-data/blob/master/scripts/notebooks/Export_base_human_to_threejs_json.ipynb

There aren't any docs yet, your best looking through old issues, the code and asking questions. Feel free to contribute even very rough docs though if you like.
