It’s not in the community plugins (yet) and still beta, so you can install it either manually or use BRAT (install it from the community plugins). BRAT makes installing it very easy.
Alternatively, the manual installation works like this.
- Go to the releases
- Download
main.js, styles.css (if available), manifest.json to your vault VaultFolder/.obsidian/plugins/your-plugin-id/.
And as always, have backups.
