Manual installation
*******************

|project_program| is a usual Python_ package and hence can be installed using the common Python_ packaging tools.
Briefly, the following steps can be used to install |project_program| from source in a system-wide location (as ``root`` user):

.. code-block:: bash

   python3 -m venv /opt/autosuspend
   /opt/autosuspend/bin/pip install git+https://github.com/languitar/autosuspend.git@<tag or branch>#egg=autosuspend[all]

.. note::

   Replace the angle brackets with desired Git tag or branch.
   Use ``main`` for the latest development release.

.. note::

   The ``all`` in the square brackets ensures that |project_program| is installed with all optional dependencies.
   That way all available checks can be used.
   In case you only need a subset of optional requirements, replace ``all`` with a comma-separated list of package extras.
   The names of these extras can be found in :file:`setup.py`.

Afterwards, copy the systemd_ unit files found in ``/opt/autosuspend/lib/systemd/system/`` to ``/etc/systemd`` and adapt the contained paths to the installation location.
