+
+This Python script provides a command-line interface for working with Game Boy ROM files. The script offers two main features:
+
+1. **Checking a checksum**: Given a checksum, the script checks if it exists in a JSON file that maps checksums to filenames. If a match is found, the script returns the filename.
+2. **Scanning a directory for ROM files**: The script scans a specified directory for Game Boy ROM files (files with a ".gb" extension), calculates the CRC-32 checksum for each file, and writes the checksums and corresponding filenames to a JSON file.
+
+The script uses standard Python libraries like `os`, `json`, and `zlib`, as well as a third-party library called `prompt_toolkit` for handling user input. 
+
+The script presents a simple menu with three options: Check a checksum, Scan the roms folder, or Exit. The user can input their choice, and the corresponding function will be called. 
+
+Overall, this Python script is a simple but useful tool for working with Game Boy ROM files from the command line.
+
+🤞The goal is to extend this toolkit to include other things I may need.
