This is the aspect of my Gemini approach to Commonplace.
[@crossingthethreshold](https://micro.blog/crossingthethreshold) [@herself](https://micro.blog/herself) it's pretty straightforward. You use Spacemacs or any other editor to write your .gmi files. Gemini protocol is very simple (not so powerful as MarkDown but powerful enough). Then you need a Gemini browser. I use Lagrange. Then you just have to create your documents and relations. But as I found Obsidian, I'm beginning to use it for my Commonplace digital books, instead of using Gemini.
