I'm a computational physics student; my work involves using multiple software with varied options. Frequently, I need to check to make sure all my parameters are correct, and having these docs at hand is important for me. Using offline documentation is always faster than Google. Since the docsets for these special pieces of software for computational physics or quantum chemistry is lacking, I build these docsets myself. Up till now, I have written code (and sometimes scrape web pages) to build these docsets myself:

1. LAMMPS: https://github.com/chazeon/lammps-docset 2. ASE: https://github.com/chazeon/ase-docset 3. VASP: https://github.com/chazeon/vasp-docset 4. QE: https://github.com/chazeon/qe-docset
