hey! the best way to figure it out might be through the official tutorial. the getting started guide is here:
https://wiki.dendron.so/notes/678c77d9-ef2c-4537-97b5-64556d6337f1/
but basically it would be:
1. Install Visual Studio Code (this along with the extension is essentially the way most use Dendron, just like you have the Obsidian app on your computer)
2. Install the Dendron extension in Visual Studio Code
