+## Installation
+
+`mailfmt` is intended for use as a standaole tool. The package is
+available on PyPI as `mailfmt`. I recommend using
+[uv](https://github.com/astral-sh/uv) or `pipx` to install it so the
+`mailfmt` command is available on your path:
+
+```sh
+uv tool install mailfmt
+```
+
+Verify that the installation was successful:
+
+```sh
+mailfmt --help
+```

 ## Markdown Safety

-HTML to be generated directly from the plain text message, and for _both_
-versions to be legible and have the same semantics.
