Is there a CMS that allows you to makes changes to your _data folder. For example, I have a file hours.yml, the code is below. If I user forestry.io, I can only access the pages.
I don’t personally have experience with using a CMS with Jekyll, but there are quite a few of them out there if you search. These are the ones I know of off hand:
I have been using Contentful. They offer a free plan based on users and content pieces uploaded. They have a netify plugin that can automate builds direct from Contenful. Contentful provides some blog posts and how-tos on Jekyll anbd Netlify integration, like this one. All content is imported as yaml into the _data directory. There are some Content Type structures that have caused import errors for me- mostly around adding Resources that cause a loop. You’ll see what I mean if you get that far. Contentful support is pretty responsive and more so if you squawk a bit. good luck.
