letsencrypt

I am setting up letsencrypt and have a few questions. I have seen the install notes http://wiki.lnxgeek.org/doku.php/howtos:let_s_encrypt_-_how_to_issue_certificates_from_a_bigip.

 

My questions are where do I download the LETSENCRYPT.TAR.GZ (I got it from http://wiki.lnxgeek.org/doku.php/howtos:let_s_encrypt_-_how_to_issue_certificates_from_a_bigip)?

 

where do I store the DOMAINS.TXT file (/shared/letsencrypt)?

 

Where do I put the hook.sh script (it was not in the tar file so do I create it)?

 

Where do I put the config script (it was not in the tar file so do I create it)?

 

what commands do I need to run to install this? I already created the DG and IRULE. I have 2 VS's (port 80 and 443).
