+# Pinned Daily Notes for Obsidian
+
+A plugin for Obsidian that helps you manage your daily notes with pinned tabs. It provides a dedicated button and command to open today's daily note in a pinned tab.
+
+## Features
+
+- Adds a ribbon icon (calendar+) to open today's daily note in a pinned tab
+- Adds a command palette action "Open today's daily note" 
+- When clicking the button or running the command:
+  - If a pinned daily note tab exists: Updates it to today's note and focuses it
+  - If no pinned daily note exists: Creates a new pinned tab with today's note
+- Works with any daily note folder structure and format
+- Respects your Daily Notes plugin settings
+
+## How to Use
+
+1. Install the plugin
+2. Click the calendar+ icon in the ribbon (left sidebar) or use the command palette to run "Open today's daily note"
+3. The first time you use it, a new pinned tab will be created
+4. Move this tab wherever you want it to stay
+5. From now on, that tab will be updated to show today's note whenever you use the plugin
+
+## Configuration
+
+No configuration needed! The plugin uses your existing Daily Notes settings for:
+- Note folder location
+- Date format
+- Other Daily Notes preferences
+
+## Installation
+
+1. Open Obsidian Settings
+2. Go to Community Plugins and disable Safe Mode
+3. Click Browse and search for "Pinned Daily Notes"
+4. Install the plugin
+5. Enable the plugin in your list of installed plugins
+
+## Support
+
+If you encounter any issues or have suggestions, please file them on [GitHub](https://github.com/docmarionum1/obsidian-pinned-daily-notes/issues).
