+# The Python Rich Package: Unleash the Power of Console Text
+
+This repository holds the sample code for the Real Python [showcase](https://realpython.com/python-rich-package).
+
+## Dependencies
+
+You should start by creating a virtual environment:
+
+```console
+$ python -m venv venv
+$ source venv/bin/activate
+```
+
+Next, install `rich` with `pip`:
+
+```console
+(venv) $ python -m pip install rich
+```
+
+The tutorial includes static sample data for the scrolling cryptocurrency table. This is also included in this repository as `crypto_data.json`. 
+If you want to download your own fresh data, then you'll need the `requests` package:
+
+```console
+(venv) $ python -m pip install requests
+```
+
+The code to perform the download is in `get_crypto_data.py`. This demo code demonstrates a single request, which it then dumps to the screen. For a real-time application, you'd need to execute this request and process the data in a loop. The [CoinLore website](https://www.coinlore.com/cryptocurrency-data-api) doesn't impose rate limits, but they suggest making at most one request per second.
