+# KoboFix Font Processor
+
+## Overview
+
+`kobofix.py` is a Python script designed to process TTF and OTF fonts for Kobo e-readers. 
+
+It generates a renamed font, fixes PANOSE information based on the filename, adjusts the baseline with the `font-line` utility, and adds a legacy `kern` table which allows the `kepub` engine for improved rendering of kerned pairs.
+
+## Requirements
+
+* **Python 3.8+**
+* **FontTools**
+
+```bash
+pip3 install fonttools
+```
+* **font-line** utility
+
+```bash
+pip3 install font-line
+```
+
+## Usage
+
+1. Open a terminal and navigate to the directory containing your font files.
+2. Run the script with a glob pattern to include all TTF/OTF files:
+
+   ```bash
+   python3 kobofix.py *.ttf
+   ```
+3. The script will:
+
+   * Validate filenames.
+   * Process each font.
+   * Apply kerning, rename, PANOSE adjustments, and baseline shift.
+   * Save output as `KC_<original_filename>`.
+
+Example:
+
+```
+Original: Lora-BoldItalic.ttf
+Processed: KC_Lora-BoldItalic.ttf
+```
