 If you want to contribute to pyastgrep, great! You'll need to:
 
+- Check out the repo using git, ``cd`` into the directory.
 
-Get test suite running::
+- Set up a venv for development. We use `uv <https://docs.astral.sh/uv/>`_ and
+  recommend you do the same. With uv, the setup instructions are::
 
-  pip install -r requirements-test.txt
-  pytest
+    uv sync
 
-Run tests against all versions::
+  This will use your default Python version. If you want to use a different
+  Python version, instead of the above do this e.g.::
 
-  pip install tox
-  tox
+    uv python install 3.10
+    uv venv --python 3.10
+    uv sync
 
-Please install `pre-commit <https://pre-commit.com/>`_ in the repo::
+- Activate the venv::
 
-  pre-commit install
+    source .venv/bin/activate
 
-This will add Git hooks to run linters when committing, which ensures our style
-(black) and other things.
+  (Alternatively, you can add ``uv run`` before most of the commands below)
 
-You can manually run these linters using::
+- Get test suite running::
 
-  pre-commit run --all --all-files
+    pytest
 
-Run mypy (we only expect it to pass on Python 3.10)::
