wget -E -k -r -p -e robots=off https://some-site.com/docs/

#### Note the following arguments:
# -E : converts downloaded HTML filenames to have a ".html" suffix
# -k : converts internal links within downloaded files to point to other downloaded files
# -r : recursively download by scanning for internal links in pages
# -p : download "page requisites", i.e. images, styles, scripts
# -e robots=off : ignore robots.txt (because some sites use it to avoid indexing)
