 When Paramecio finish the installing, you can create your first paramecio site with `paramecio` command.
 
+> If you install passlib and bcrypt python modules, your paramecio install will use bcrypt algorithm for crypt system passwords. If not, use default system implementation hash algorithm (normally the more strong algorithm available).
