Front matter templates are not generated by Forestry

Front Matter Templates are not generated. Followed this tutorial https://www.youtube.com/watch?v=ResipmZmpDU but Forestry didn't generate front matter templates that are available in the exampleSite folder. The website is deployed by Netlify but some bits of the homepage are not shown and no other page is rendered, so it is basically just some portion of the homepage and that's all, other content is not rendered by Netlify. What could be the reasons? Is there a way to skip Forestry? I am using the Educenter theme.

I mean I can probably create those front matter template at Forestry but I do not even understand why that would be necessary. The website is rendered locally just fine without using Forestry. The exampleSite folder comes with the forestry folder and front matter templates in it and I do not understand how they were created: by Forestry automatically or by ThemeFisher. Therefore I do not understand what I am supposed to do with them -- to create those templates or Forestry will create them for me? Obviously I have some folders in the /content beyond the pre-existing folders like "courses". And it is not clear from the documentation, in fact it doesn't say anything about them, how to go about those templates. For example I copied front matter templates from exampleSite into the forestry folder of my website, pushed to GitHub, those changes were deployed by Netlify but nothing happened -- the "Courses" page is not rendered even though I didn't change it, it remains the same as in the sample site. So this all is quite confusing.

Why use Forestry in the first place?

Why not just rely on Netlify solely without using Forestry or other 3rd party services?

How are front matter templates generated and who generates them? Forestry does that automatically upon importing the website source code from GitHub, or I have to do it?
