+# Building Packages
+
+Released packages are [built and published via GitHub actions](maintainers.md#drafting-releases).
+
+## Python packages
+
+To build Python packages locally for testing, use [`task`](starting-dev-server.md#without-dev-containers). After installing `task`, run `task py:package` to perform all the steps needed to build the package and a requirements file. To do it manually, run:
+```sh
+pushd frontend
+yarnpkg install
+yarnpkg generate
+popd
+rm -r mealie/frontend
+cp -a frontend/dist mealie/frontend
+poetry build
+poetry export -n --only=main --extras=pgsql --output=dist/requirements.txt
+MEALIE_VERSION=$(poetry version --short)
+echo "mealie[pgsql]==${MEALIE_VERSION} \\" >> dist/requirements.txt
+poetry run pip hash dist/mealie-${MEALIE_VERSION}-py3-none-any.whl | tail -n1 | tr -d '\n' >> dist/requirements.txt
+echo " \\" >> dist/requirements.txt
+poetry run pip hash dist/mealie-${MEALIE_VERSION}.tar.gz | tail -n1 >> dist/requirements.txt
+```
+
+The Python package can be installed with all of its dependencies pinned to the versions tested by the developers with:
+```sh
+pip3 install -r dist/requirements.txt --find-links dist
+```
+
+To install with the latest but still compatible dependency versions, instead run `pip3 install dist/mealie-$VERSION-py3-none-any.whl` (where `$VERSION` is the version of mealie to install).
+
+## Docker image
+One way to build the Docker image is to run the following command in the project root directory:
+```sh
+docker build --tag mealie:dev --file docker/Dockerfile --build-arg COMMIT=$(git rev-parse HEAD) .
+```
+
+The Docker image can be built from the pre-built Python packages with the task command `task docker:build-from-package`. This is equivalent to:
+```sh
+docker build --tag mealie:dev --file docker/Dockerfile --build-arg COMMIT=$(git rev-parse HEAD) --build-context packages=dist .
+```
