 # Installation
 * save the script in home directory of Mastodon (eg. ~/bin, not under /root, maybe /usr/local/bin)
 * make the script executable (e.g. `chown mastodon:mastodon bin/cleanup-mastodon-users.sh && chmod u+rx bin/cleanup-mastodon-users.sh)`
+* create a config file at `$HOME/.cleanup-mastodon-users.conf` by calling the script with `--init` argument and edit the file to fit your needs
 * create a crontab to execute the script, e.g.: `20 8    * * 4   /home/mastodon/bin/cleanup-mastodon-users.sh --dowhatimean` to execute the script every week. In the example it is executed every Thursday (4th day of week) at 8:20 in the morning. 
 * for the first runs you should set `UPPERLIMIT` to a high number and keep the deleting of the user commented out (`${mastodonpath}/bin/tootctl accounts delete "${username}"`). After the first few runs you can reduce `UPPERLIMIT` to a lower setting and repeat this until you reached the final value. You shouldn't have too many weeks between `LOWERLIMIT` and `UPPERLIMIT`. Sensible values might be 6 and 7 months or 12 and 13 months or so.  
 * change the variables at the begin of the script to your site settings.
