+# Development
+
+> All changes MUST follow the vendor/tiara-gitflow-spec.git and no work MUST be
+> started without a TODO issue.
+
+## Prerequisites
+
+- Python 3.9+
+- [Pipenv](https://pipenv.pypa.io/)
+- [tox](https://tox.wiki/) (installed via Pipenv dev dependencies)
+- Node.js (for the `@byteb4rb1e/mime-todo` issue tracker CLI)
+
+## Setup
+
+Iniitialize Git submodules:
+
+```bash
+git submodule update --init --remote --recursive
+```
+
+Install dependencies (includes the package in editable mode):
+
+```bash
+pipenv install --dev
+```
+
+
+## Tooling
+
+### Package
+
+The project is packaged as `byteb4rb1e.utils` under a namespace package
+layout (`src/byteb4rb1e/utils/`). It is installed in editable mode via
+Pipenv.
+
+Build a distribution:
+
+```bash
+pipenv run dist
+```
+
+### Testing
+
+Tests are managed by tox. Test environments are defined in `tox.ini`:
+
+```bash
+# run all test suites
+tox
+
+# run specific environments
+tox -e unit-py313
+tox -e lint
+tox -e format
+```
+
+| Environment | Purpose |
+|---|---|
+| `unit-py3{9-13}` | Unit tests |
+| `smoke-py3{9-13}` | Smoke tests |
+| `integration-py3{9-13}` | Integration tests |
+| `lint` | Type checking (mypy) |
+| `format` | Code style (autopep8) |
+| `audit` | Dependency audit (pip-audit) |
+
+### Issue tracker
+
+Issues are tracked in the `TODO` file using the
+[MIME TODO](https://specs.code.tiararodney.com/mime-todo/) format. Use the
+`@byteb4rb1e/mime-todo` CLI to interact with it:
+
+```bash
+# list issues
+npx @byteb4rb1e/mime-todo list
+
+# show a specific issue
+npx @byteb4rb1e/mime-todo show 3
+
+# create an issue
+npx @byteb4rb1e/mime-todo create --type feature --title "Title" --plan "Description" --module homeostat
+```
+
+See [CONTRIBUTING.md](CONTRIBUTING.md) for the full issue lifecycle.
+
+### Publishing
+
+Build wheel and source distributions:
+
+```sh
+pipenv run sdist
+```
+
+Configure publishing options:
+
+`~/.pypirc`
+```
+[distutils]
+index-servers =
+    tiararodney
+
+[tiararodney]
+repository: https://pypi.code.tiararodney.com/root/byteb4rb1e/
+username: <username>
+password: <password>
+```
+
+Publish to pypi.code.tiararodney.com:
+
+```sh
+pipenv run sdist:publish:tiarardoney
+```
+
+
+## Project layout
+
+```

-'configure' configures this package to adapt to many kinds of systems.
-
-Usage: $0 [OPTION]... [VAR=VALUE]...
-
-To assign environment variables (e.g., CC, CFLAGS...), specify them as
-VAR=VALUE.  See below for descriptions of some of the useful variables.
-
-Defaults for the options are specified in brackets.
-
-Configuration:
-  -h, --help              display this help and exit
-      --help=short        display options specific to this package
-      --help=recursive    display the short help of all the included packages
-  -V, --version           display version information and exit
-  -q, --quiet, --silent   do not print 'checking ...' messages
-      --cache-file=FILE   cache test results in FILE [disabled]
-  -C, --config-cache      alias for '--cache-file=config.cache'
-  -n, --no-create         do not create output files
-      --srcdir=DIR        find the sources in DIR [configure dir or '..']
-
-Installation directories:
-  --prefix=PREFIX         install architecture-independent files in PREFIX
-                          [$ac_default_prefix]
-  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
-                          [PREFIX]
-
-By default, 'make install' will install all the files in
-'$ac_default_prefix/bin', '$ac_default_prefix/lib' etc.  You can specify
-an installation prefix other than '$ac_default_prefix' using '--prefix',
-for instance '--prefix=\$HOME'.
-
-For better control, use the options below.
