+
+Modify ${MY_CONF} according to your preferences.
+Assuming you place the database into ${MY_DBDIR}
+(recommended), execute the following commands in a root shell:
+
+mkdir -m 0770 ${MY_DBDIR}
+chgrp clamav ${MY_DBDIR}
+sudo -u clamav -- fangfrisch -c ${MY_CONF} initdb

+You can now enable /etc/cron.d/${PN} for periodic updates.
+
+### Alternative: Updating from release 1.0.1:
+
+Either create a fresh database or manually delete all existing
+database tables, then run the initdb command as shown above."
