Opening in MindNode?

Hi. I just dl’d Obsidian this morning, quickly perused the help file, and then came to the forums for the sample workflows. After unzipping the workflows folder I double-clicked on 01 Obsidian Workflows.md and it opened in MindNode. In fact, according to the Finder, Obsidian was not one of the recommended apps for opening it. Anyway, I forced the finder to attempt to open it in Obsidian, but I couldn’t see anywhere it had done so. Where have I gone wrong?

Open Obsidian, then select the folder with your notes as a vault. MindNode is most likely your default editor for markdown files. See also Have Obsidian be the handler of .md files (file association)
