From the docs/ directory, build the docs by running
make buildThis will first install any required dependencies and build the html files. (the next time you can simply do make html).
To open the built docs, run
make openwhich makes use of the command open. If you're on Linux and open does not work you can add alias open='xdg-open to your rc-file.
To both build the html files and open them, run
make see
