 # resvg-py
 
-## Usage
+`resvg-py` provides a Python interface to the `resvg` library, an open-source SVG rendering library that can be used to convert SVG images to various other formats such as PNG, PDF, and SVGZ.
+
+The purpose of `resvg-py` is to provide a convenient way to use `resvg` from within Python code, without the need for external dependencies.  By using `resvg-py`, developers can incorporate SVG rendering functionality directly into their Python applications, making it easier to work with SVG images and to create high-quality, scalable graphics for their projects.
+
+With `resvg-py`, developers can:
+
+* Load SVG files and render them to various output formats
+* Control the output size, resolution, and quality of the rendered images
+* Modify SVG documents programmatically before rendering
+* Work with SVG images directly within their Python code, without the need for external tools or libraries
+
+Overall, `resvg-py` provides a simple and powerful way to work with SVG images in Python, and can be a useful tool for developers who need to work with vector graphics in their projects.
