The Gist plugin for Obsidian allows you to embed GitHub Gists in your notes, providing an easy way to share and collaborate on code snippets. With this plugin, you can render Gists with just a simple fenced code block, specifying either the Gist ID or both the username and Gist ID. You can also specify which files within the Gist to display, making it perfect for referencing specific parts of a large codebase. The plugin is easy to install, either through the Obsidian app store or manually by copying files into your vault's plugins directory.
