The Save as Gist plugin allows users to save their current Obsidian file or a selected portion of it as a private GitHub Gist. This plugin streamlines the process of sharing or storing notes securely on GitHub. Users need to generate a GitHub API token with the 'Create Gist' permission and configure it in the plugin settings. Upon creating a Gist, the plugin automatically copies the Gist URL to the clipboard for quick access. Note that the plugin only supports private Gists and does not allow updates to existing Gists.
