Please can anyone help me, I would like to set up multistore on localhost, prior to uploading to live domains. I want to test it out, and add a few more mods etc.

I have searched for this info in this forum, and several people have asked before, but always seem to say something like "Oh I found out how to do it"... before guidance was posted.

I have installed v1.3.9d, and have added Multistore to that.., all on localhost/site1. Admin is fine, but if I navigate to localhost/site1/ I get this error message "the domain localhost does not exist".. I assume that is because I need to sort out config files...

Does anyone have a set of instructions I could borrow on how to set things up on localhost (I want main store plus 2)... then how to transfer to live environment later.

Apologies if this has been answered before, but I just couldn't find it.

Thanks in advance for all/any help you are able to provide.
