If you want to use GitHub to publish your changes, first create a fork of datasette under your own GitHub account. Now clone that repository somewhere on your computer: git clone git@github.com:YOURNAME/datasette If you want to get started without creating your own fork, you can do this instead: git clone git@github.com:simonw/datasette The quickest way to set up a development environment is to use uv . From the repository root you can run the tests directly: cd datasette uv run pytest This will create a local .venv/ and install Datasette plus its development dependencies. If you prefer to manage your own virtual environment with pip, create and activate one and then install the development dependency group: python3 -m venv ./venv source venv/bin/activate python3 -m pip install -e . --group dev","[""Contributing""]","[{""href"": ""https://docs.python-guide.org/starting/install3/osx/"", ""label"": ""is using homebrew""}, {""href"": ""https://github.com/simonw/datasette/fork"", ""label"": ""create a fork of datasette""}, {""href"": ""https://github.com/astral-sh/uv"", ""label"": ""uv""}]"
