+# Developing for `darwin-py`
+
+`darwin-py` uses a `pyproject.toml` file, and manages it with `poetry`

+  - [The `pyproject.toml` file](#the-pyprojecttoml-file)
+
+
+## Development environment
+
+You can either:
+* Install a `poetry` environment, and work with that, or
+* Install `darwin-py` using `pip` from Pypi.org, and make your own arrangements for debugging.
+
+The recommended setup is to install poetry, and use this to setup a dev environment:
+
+```sh
+$ python --version  # must be 3.9 or greater for development tools
+$ pip install poetry
+$ poetry install --extras "test ml medical dev" -G dev
+```
+
+This creates a `virtualenv` for the project.  If you prefer, you can use `venv` by running this command before `poetry install`:
+
+```sh
+$ python -m venv .venv
+```
+
+You can give it a different name if you wish, but the name `.venv` is pre-ignored in the `.gitignore` file.
+
+
+## Basic poetry commands
+
+### Add a package to general dependencies:
+```sh
+$ poetry add [PACKAGENAME]
+```
+
+
+### Add a package to one of the extras groups
+
+(these are those that are used in `pip install darwinpy[option]` type commands - ours are `test`, `ml`, `medical`, and `dev` - `dev` is for developers who don't want to use poetry - so they can install using `pip`)
+
+```sh
+$ poetry add [PACKAGENAME] --extras="extra group names"
+```
+
+
+Packages added this way will be installable with `pip` once a release has been made to PyPi.
+
+
+### Add a package to the poetry dev dependencies
+
+```sh
+$ poetry add [PACKAGENAME] -G groupname
+```
+
+Currently the only group is `dev` and contains dev tools for developers using `poetry`.  `poetry` groups have no effect on packaging, and things installed here will not be packaged.
+
+## The `pyproject.toml` file
+
+This was a necessary change for PEP-517, but also allows us a central place to add configuration.
+
+Items in the `pyproject.toml` file that are grouped as `[tool.X]` are configuration settings for specific tools on the system.
+
+For example, settings for `mypy` static type analyser, are in the `[tool.mypy]` group.
+
+A plugin is installed that allows `flake8` to take its configuration from this file, even though usually it only works with `setup.cfg` and `.flake8`.
