The plugin enables straightforward operations, including initializing a repository, committing changes, and syncing with a remote repository directly within the Obsidian interface. Users can quickly commit changes with custom messages and optionally push them immediately to a remote. The integration simplifies version control and backup tasks, offering a seamless workflow for anyone looking to maintain a secure, version-controlled Obsidian vault.
