Destination e-mail address for bootstrap contact form

Hello,
Very many thanks for your help.
I have copied your FORM section to index.html
and uploaded the template to
http://www.lecba-rakoviny-v-zahranici.cz/

Can you please write me what I shall do now? (pls step by step so that I can understand)

Also, what is the purpose of the Password functionality? Do I need it?

Where shall I put the destination email address?
Very many thanks again!
Jan
