 # Single Poker Hand Ranking Service
-## Requirements
-This service comprises an API to compute the rank of an individual poker hand. The requirements are to:
+
+This project started as a take-home interview task for an MLOps Engineer role. It is a very simple calculation I've wildly overengineered into a demonstration of how I go about building APIs.
+
+## Project Scope
+
+This service comprises an API to compute the rank of an individual poker hand. The scope of this project is to:
 
 - Write an algorithm that takes a hand of cards and identifies the ranking of the given hand.
 - Expose an API to serve this algorithm via an endpoint `/rank`, that accepts a valid poker hand and returns its ranking.

 - Python 3.11
 - [Poetry](https://python-poetry.org/)
 - [GNU Make](https://www.gnu.org/software/make/)
 
 ## Usage
+
 - Install with `make install`.
 - Run linting and tests with `make quality test coverage clean`.
-- Run API with `make API`.
+- Build the API container with `make build`, then run API with `docker compose up -d`.
 - Check API health with `curl localhost:8000`
 - Query API for rank with e.g.
