+# Sublime Text `.tmTheme` to CSS File Converter
+
+This is a very simple utility that exposes [syntect](https://github.com/trishume/syntect)'s built in capability to load
+and parse Sublime Text `.tmTheme`-format themes and emit equivalent CSS themes for use with syntect's syntax
+highlighting.
+
+This utility was put together so that it is a simple matter of running a quick command via the CLI to do this
+rather than having to write some small bit of code yourself to do the same thing via syntect.
+
+## Usage
+
+```text
+syntax_to_css /path/to/your-theme.tmTheme
+```
+
+This will result in a CSS file being written to `/path/to/your-theme.css`.
+
+## Obtaining Themes
+
+You can of course use anyone's custom Sublime Text themes with this tool, provided they are distributed in `.tmTheme`
+format and **not** as `.sublime-theme` files.
+
+Alternatively, if you just want to generate CSS files from Sublime Text's default built-in themes, you can grab these
+from your Sublime Text install. The location of these files will vary, but for example if on a Linux system you
+installed Sublime Text to `/opt/sublime_text`, you can find a file at `/opt/sublime_text/Packages/Color Scheme - Legacy.sublime-package`
+which is actually just a ZIP archive with a different file extension. Inside this archive you can find a number of
+different `.tmTheme`-format themes that you can use with this tool to generate CSS files from.
