+# Development Instructions
+
+## Requirements
+
+- Python >= 3.9
+- pip >= 19 (for installation)
+
+## Testing
+
+To lint the `bitbake-setup` pypi packaging, run the ruff tool.
+```bash
+ruff check bin/bitbake-setup packaging-pypi/bitbake-setup
+```
+
+The steps to build and test the `bitbake-setup` pypi packaging have been automated with the `bitbake-selftest` tool. This tool automatically creates a Python virtual environment for you.
+
+Run the bitbake-selftest
+```bash
+BB_SKIP_PYPI_TESTS=no bin/bitbake-selftest -v bb.tests.setup.PyPIPackagingTest
+```
+
+## Packaging
+
+### Create the development sandbox
+
+To create the development sandbox run:
+```bash
+packaging-pypi/bitbake-setup/package-bitbake-setup.py
+cd packaging-workspace
+```
+
+### Updating the vendored modules
+
+You may use the Python vendoring module to update the vendored modules. Its configuration can be found in the pyproject.toml under the tool.vendoring section.
+
+This information includes:
+- the destination directory where the vendored modules are stored (e.g. lib/bb/_vendor)
+- the module names and versions to vendor are found in the requirements file vendor.txt
+- the namespace to place the modules in (eg. bb._vendor)
+- the patches to apply to the pristine source code (eg. vendor/patches)
+
+To run the tool you may install it from pypi and run it from the top-level directory.
+
+```bash
+python3 -m pip install vendoring
+vendoring sync .
+```
+
+### Building the package
+
+To install the development tools manually run:
+```bash
+python3 -m pip install -e '.[dev]'
+```
+
+To build a wheel (.whl) then use:
+```bash
+python3 -m build
+```
+
+This produces a wheel (.whl) file in the dist directory. This may be installed using pip.
+
+### Installing the package
+
+```bash
+python3 -m pip install dist/bitbake_setup-*-py3-none-any.whl
+```
