I have seen flake-parts used in many nix codebases and I am wondering if there are any blogs, guides u would recommend since the documentation is not kind of high level for me.
Do you have some specific questions in mind? IME the flake.parts website, especially how pluggable modules (this one and neighboring pages) was very helpful.
Sorry for not being explicit in the question. I am only looking for a blog post that discuss why we need flake-parts and how to use it.
There’s a bit of my opinion on this in this blog post. I don’t go into the details and benefits of flake.parts specifically, but it’s something I thought about writing – thus asking for specific prompts 
This was an awesome read. Thanks
