Technical document for LAMMPS

Dear LAMMPS developers

I should admit the incredibly easy reading LAMMPS manual which mirrors the hard works of developers and its authors.
However, based on many communications in the mailing list, I realized the lack of a Technical document along with the present manual for explaining the mathematical formulation and anything taken for LAMMPS development working in the background. Many other softwares, either academic or commercial, offers such documentation.

Is there any plan for that purpose? or other alternatives?

please provide an example for such a “technical document” for some other (open source?) MD software.

thanks,
