Manual - Task Genius

Download the latest release files (main.js, manifest.json, styles.css) from the Task Genius Releases page on GitHub.
Navigate to your Obsidian vault's plugins folder. This is usually located at YourVault/.obsidian/plugins/ (Note: .obsidian might be a hidden folder).
Create a new folder inside the plugins directory named exactly task-genius.
Copy the downloaded main.js, manifest.json, and styles.css files directly into this new task-genius folder.
Reload Obsidian (Close and reopen the app, or use the command Reload app without saving).
Go back to Settings -> Community plugins and enable "Task Genius".
