+# Oh My Zsh Backup Plugin
+
+This plugin provides a convenient way to back up your `~/.zshrc` file locally and to a GitHub repository. It automatically detects changes in the `.zshrc` file, commits them with a timestamped message, and pushes changes to the specified GitHub repository. If you ever rm your zshrc, simply go to your Github repo and check it out.
+
+## Dependencies
+1. Locally installed git with a git config for pulling the repo url and username
+2. A repo in Github https://github.com/yourusername/oh-my-zsh-backup
+    Example: https://github.com/yourusername/oh-my-zsh-backup
+3. Push privileges configured to the main/master origin branch
+4. Create directory privileges for this script - create "$HOME/projects/backups" manually otherwise
+
+## Installation
+
+1. Clone this repository into your Oh My Zsh custom plugins directory:
+
+   ```bash
+   git clone https://github.com/yourusername/oh-my-zsh-backup ~/.oh-my-zsh/custom/plugins/backup
+   ```
+
+2. Add `backup` to the plugins array in your `~/.zshrc` file:
+
+   ```bash
+   plugins=(... backup)
+   ```
+
+3. Restart your terminal.
+
+## Usage
+
+Simply open your terminal or source your `~/.zshrc` file, and the backup will be triggered automatically. Any changes detected in `~/.zshrc` will be backed up to the specified GitHub repository.
+
+## Configuration
+
+### GitHub Username
+
+If your GitHub username is not already set globally, the plugin will prompt you to enter it the first time you run it. Alternatively, you can set it manually using:
+
+```bash
+git config --global user.name "Your Username"
+```
+
+### Branch
+
+By default, the plugin pushes changes to the branch specified GitHub repository is checked out to locally in the "$HOME/projects/backups" backup directory. You can change the target branch by checking out to a new branch in the backup directory.
+
+## Contributions
+
+Contributions are welcome! If you encounter any issues or have suggestions for improvements, please feel free to open an issue or submit a pull request on GitHub.
+
+## License
