     To capture sites that require a user to be logged in, you must specify a path to a chrome profile (which loads the cookies needed for the user to be logged in).  If you don't have an existing chrome profile, create one with `chromium-browser --disable-gpu --user-data-dir=/tmp/chrome-profile`, and log into the sites you need.  Then set `CHROME_USER_DATA_DIR=/tmp/chrome-profile` to make Bookmark Archiver use that profile.
