getting a small site into get-simple

[lenb]

I've been reading the wiki and I am not finding anything that will help me get a pre-existing site into GetSimple. The wiki does not appear to address this problem. Also, see nothing about GS tags.

I'm afraid that at this point, I am to ignorant to even understand the reply posts. Yojo replied as below and I have no idea what it means.

add basic GS tags (see wiki) into your html template > save template as .php file > upload your template.
Everything you need to know is described in wiki.

My main goal is to be able to allow users to edit content safely. I see nothing about how I limit the sort of access which users may have (assuming I create multiple users with the multi-user plugin).

Is this possible in GetSimple.

Thanks.
