 # Bootstrap for Python coding kata
 
 [![CI](https://github.com/Coding-Cuddles/bootstrap-python-kata/actions/workflows/main.yml/badge.svg)](https://github.com/Coding-Cuddles/bootstrap-python-kata/actions/workflows/main.yml)

-## Overview
-
-This is a bootstrap repository for clean code katas in Python 3 using pytest.
+Start a Python coding kata with pytest. Setup is complete when the starter test passes.
 
 ## Prerequisites
 
-- [Python 3.8+](https://www.python.org/)
-- [pytest](https://pytest.org)
+Required:
+
+- [Git](https://git-scm.com/downloads)
+- [uv](https://docs.astral.sh/uv/getting-started/installation/)
+
+Optional:
+
+- [GNU Make](https://www.gnu.org/software/make/), for shorter commands. Every required task also
+  has a direct `uv` command.
+
+You do not need to install Python or pytest separately. `uv` installs a compatible Python version
+and the locked project dependencies when needed.
+
+## Set up the kata
+
+1. Clone the repository:
+
+   ```console
+   git clone https://github.com/Coding-Cuddles/bootstrap-python-kata.git
+   ```
+
+2. Enter the repository directory:
+
+   ```console
+   cd bootstrap-python-kata
+   ```
+
+3. Run the starter test. Use Make when it is installed:
+
+   ```console
+   make test
+   ```
+
+   Otherwise, run pytest through `uv` directly:
+
+   ```console
+   uv run pytest
+   ```
+
+   The first run may install Python and the project dependencies. Setup is complete when pytest
+   reports `1 passed`.
+
+   If the command fails with `uv: command not found`, install
+   [uv](https://docs.astral.sh/uv/getting-started/installation/) and repeat this step.
+
+## Work on the kata
+
+1. Replace the starter assertions in `test_something.py` with the first kata test.
+
+2. Run the tests after each change. Use Make when it is installed:
+
+   ```console
+   make test
+   ```
+
+   Otherwise, run pytest through `uv` directly:
+
+   ```console
+   uv run pytest
+   ```
+
+   Continue when the test run passes.
 
-## Usage
+## Make command reference
 
-### Run tests
+Make is optional. Run `make` or `make help` to list these commands in the terminal.
 
-```console
-make test
-```
+| Command             | Result                                  |
+| ------------------- | --------------------------------------- |
+| `make all`          | Run the test suite                      |
+| `make test`         | Run the test suite                      |
+| `make format`       | Format tracked Python files             |
+| `make format-check` | Check formatting without changing files |
+| `make clean`        | Remove generated caches                 |
