+# Font to Binary Conversion Script
 
+This script uses the following libraries:
+
+- **Pillow** (a fork of PIL): to load and manipulate the font image  
+- **numpy**: to convert glyph images to binary arrays  
+
+## Script Functionality
+
+The script performs the following steps:
+
+1. Extracts the glyphs from the input TrueType font file using Pillow's `ImageFont` class.  
+2. Creates a binary representation of each glyph by converting it to an array and packing it into bytes using `struct.pack`.  
+3. Saves the binary font data to a file named after the input font file but with `_binary.bin` appended (e.g., `arial.ttf_binary.bin`).  
+4. Generates a `README.md` file describing the parameters used for generating the binary font and the output files produced.  
+
+## Usage
+
+Run the script from the command line as follows:
+```bash
+ python font_to_binary.py your_font_file.ttf out.h
+```
+
+Replace `your_font_file.ttf` with the path to your TrueType font file (for example, `arial.ttf`). 
+Replace `out.h` with the path to your TrueType font file (for example, `font_map.h`).
