 ## Introduction
 
-`crf2html` is a command-line utility inspired by the Thief series of video games, including Thief: The Dark Project (Thief Gold) and Thief II: The Metal Age. In these classic games, textures and images were stored in proprietary formats like CRF and PCX. The tool aims to bring a piece of that nostalgic world to modern web development.
-
-The program is designed to generate an HTML page that beautifully showcases the textures found in Thief series CRF files and other image formats (PCX, GIF, PNG, and JPG). It seamlessly resizes and encodes these textures as base64, making it easy to embed them in an organized HTML page.
-
-Whether you're a fan of the Thief series or simply interested in working with these classic texture formats, `crf2html` provides a convenient way to create galleries and showcases of these vintage textures for various creative and nostalgic purposes.
-
-> The project primarily draws inspiration from [/vfig/thieftextures](https://github.com/vfig/thieftextures), which is a Python program.
+The `crf2html` program generates an HTML page that displays image textures from a specified directory or a CRF/ZIP file. The tool resizes the images, encodes them as base64, and organizes them into a neat HTML page.
 
 ## Features
 
-- Converts Thief series textures and other image formats to base64 for easy embedding in an HTML page.
-- Organizes textures by family and sorts them alphabetically by caption.
-- Allows customization of the page title, so you can give your texture showcase a unique name.
-- Supports various image formats, including PCX, GIF, PNG, and JPG.
-- Provides an option to specify a custom background color for the images.
-- Generates a clean and organized HTML page with embedded textures, reminiscent of the Thief games' texture menus.
+- Read image files from both directories and CRF/ZIP files.
+- Supports multiple image formats including `.pcx`, `.gif`, `.png`, `.jpg`, and `.tga`.
+- Ability to resize images and encode them as base64 for inline embedding in HTML.
+- Organizes images by families, based on their directory or path structure.
+- Easily customizable output through command-line arguments.
