@Laura - Procedure on adding additional hosts is missing. Could you please include it as a part of setup procedure
Laura, you will have to add the content present in the link  below for adding additional hosts. Remember we have already discussed about this during beta and you prepared a draft for this and said you will publish it soon.
Laura, in 8.4 section you can remove steps 6 and 7 and ask the user to perform steps in step 4 and 5 of 8.2 section.
changes in section 8.4 looks good to me. Moving this to verified state.
