As detailed in Hosting this blog, despite wanting to use Joplin for note-taking, I ended up using Obsidian. Don't get me wrong, I like Obsidian very much, but I wanted to go as FOSS as I could. However, I couldn't get the blogging software working correctly with Joplin, so I went with Obsidian.
Install
To get Obsidian working on my newly Mint-ed (lol) laptop install, it was extremely easy. I had started this blog in Windows, so as part of backing up all of my laptop documents I also backed up my Obsidian vaults. After I installed Mint on my laptop I installed Obsidian by going to Mint's "Software Manager" and searching for "Obsidian". It popped right up. I clicked on the "Install" button and waited for everything to install. I started Obsidian and opened the vault, and everything just worked, including the Digital Garden plugin. I didn't even have to re-install the token!
The reason I have "Note-taking" after "Syncthing" is because Syncthing is how I'm going to synchronize my vaults between my laptop and my phone. In reality I did it after, because I'm documenting everything in Obsidian as I complete each task. But you will have to have 3. Syncthing completed before making the changes below for synchronizing your vaults.
