Best way to present child care "Parent Handbook" information to families on webpages instead of a PDF

Hi Community, 

Parents at child care centres often get a Parent Handbook emailed to them as a PDF. Most parents read this information on their phones and a A4 PDF, even with links and larger text, it isn't very user friendly on mobile (or desktop for that matter). I had the idea to present this information to parents on our Squarespace website instead.

Here's an example of a Parent Handbook PDF from another provider: https://www.kidsclubchildcare.com.au/wp-content/uploads/2020/10/20200721-KidsClub_Parent_Tour_Book_Portrait_V5.pdf

Ideally, I thought this could sit on a sub domain (e.g. handbook.websitename.com.au) and create a "mini website" with the search function turned on and use the main navigation with several pages and subpages so they can find their way around easily. If I do this, do I need to create a whole new Squarespace site and pay for another subscription? I won't link have a link on our main website to this subdomain as it's only for parents (understand it'll still be searchable on the web and that's fine). 

The other option I thought I could do, was use the "Portfolio" collection to help organise this information. I would make this a non-linked collection on the website. Using "Portfolio" would let me drag around the order of the sections, and it gives the user the "go back to previous page" "go forward to next page" functionality at the bottom of the pages to help them read through the information. I could add a bar or button to the top and bottom of each "Portfolio" page that links back to the whole "Portfolio". 

I'd be grateful for any advice - thank you!

Instead of using the Portfolio feature, it may make more sense to use a Blog, which would also automatically set up the next page for you.

• You can copy each blog to keep the formatting the same.
• You can set up a title card for each blog.
• You could set up a navigation at the top or bottom of each blog post that links to each one, so that they can easily move through the content.
• If it would be helpful, you can use a Summary Block to pull all the title cards and have them display on a page with information for the parents. 

Keep in mind though that people tend to read less on their phones, so you could pair it down and just make a landing page with all this content.

Hi WCS, I was initially going to use the Blog feature but it looked like if I wanted to order or re-order the content, or add a new section, I'd have to tweak the "date" of the post - this seemed a bit limited.

In regards to my other question, if I wanted to create a sub domain (e.g. handbook.websitename.com.au) and create a "mini website" to help users navigate the content, do I need to create a whole new Squarespace site and pay for another subscription?

Thank you for your help!
