 PISpy aims to be a simple but useful [PyPi](https://pypi.org/) lookup client
 for the Terminal, built with [Textual](https://textual.textualize.io/).
 
+## Installation
+
+PISPy is a full-screen terminal-based tool and is best installed using
+[`pipx`](https://pypa.github.io/pipx/):
+
+```sh
+$ pipx install pispy-client
+```
+
+## Running
+
+Once installed, just run `pispy` from your shell.

+
+## Naming
+
+> Wait! What? Is this pispy or pispy-client? Why the two names?
+
+Well... when I started hacking this together I went to check if PyPi had a
+package called `pispy` and it didn't, so I steamed ahead with that. Only
+when I came to add the package to PyPi did it say it wouldn't let me because
+it was too similar to another package.
+
+So... package name is `pispy-client` but the content is `pispy`.
+
 ## Work in progress
 
 PISpy is currently a work in progress. I'm still figuring out what it should
 do and how; but for now it provides a simple package lookup interface.
