+# PDF Plugin for Oh My Zsh
+
+This plugin provides a convenient way to manage and open PDF files from your terminal using fuzzy finding.
+
+## Features
+
+- Automatically detects available PDF readers (okular, evince, xpdf, firefox, and some others)
+- Creates and maintains a list of PDF files in your home directory
+- Uses `fzf` for fuzzy finding and selecting PDF files
+- Fallback to `find` command if `fd` is not available
+
+
+## Requirements
+
+- Zsh with Oh My Zsh framework
+- Any suitable PDF reader (e.g., okular, evince, xpdf, firefox, zathura, mupdf, qpdfview, atril)
+- `fzf` for fuzzy finding (recommended)
+- `fd` command (optional, improves file search performance)
+
+
+
+1. Activate the plugin in `~/.zshrc`:
+
+   ```zsh
+   plugins=(... pdf)
+   ```
+
+2. Restart your shell or run:
+
+   ```zsh
+   source ~/.zshrc
+   ```
+
+## Usage
+Example usage:
+
+```zsh
+# Open fzf to select a PDF
+pdf
+
+# Open a specific PDF file
+pdf ~/Documents/example.pdf
+```
+## Configuration
+
+The plugin will automatically create a directory `~/.config/pdfiledoc/` and a file `pdfs.txt` to store the list of PDF files. This list is updated when:
+
+- The `pdfs.txt` file doesn't exist
+- No PDF is selected from the existing list
