just like Obsidian, it's definitely about writing things, and organizing those writings. Dendron's main claim to fame is that it is hierarchical, meaning knowledge always exists somewhere in a hierarchy. you can think of it like a branch.

├── journal
│   ├── journal.heres-some-journal
│   └── journal.some-other-journal
├── philosophy
│   ├── nihilism
│   ├── absurdism
│   └── ethics

i'm not sure if this makes the most sense. but essentially notes in dendron have a context, that is they sit somewhere in a hierarchy. just like a tree. the best way to learn though is probably by doing, and the tutorial would be a good start! i also came from obsidian 🙂
