+# Reminder Script
+
+This script allows you to set reminders from the command line on a Linux system. It uses the `notify-send` command to display pop-up notifications and the `at` command to schedule these notifications at specified times.
+
+## Features
+
+- Set reminders with custom messages.
+- Schedule reminders for specific times or intervals.
+- Display notifications as pop-ups on your desktop.
+
+## Requirements
+
+- `libnotify-bin` package for `notify-send` command.
+- `at` command for scheduling tasks.
+
+## Installation
+
+1. **Clone the Repository**:
+   Clone this repository to your local machine:
+   ```bash
+   git clone <repository-url>
+   cd <repository-directory>
+   ```
+
+2. **Install Necessary Packages**:
+   Ensure you have the `libnotify-bin` package installed. For Fedora, you can install it using:
+   ```bash
+   sudo dnf install libnotify
+   ```
+
+3. **Make the Script Executable**:
+   Make the script executable by running:
+   ```bash
+   chmod +x remind.sh
+   ```
+
+## Usage
+
+- **Set a Reminder**:
+  Use the script to set reminders with a message and time. For example:
+  ```bash
+  ./remind.sh "Time to take a break" in 5 minutes
+  ```
+
+- **Set a Reminder for a Specific Time**:
+  ```bash
+  ./remind.sh "Meeting starts" at 14:00
+  ```
+
+- **Immediate Reminder**:
+  ```bash
+  ./remind.sh "Check emails" now
+  ```
+
+## Notes
+
+- Ensure your desktop environment's notification system is enabled.
+- The `at` command must be running on your system to schedule tasks.
