Optional but recommended:
* [chromaprint](https://acoustid.org/chromaprint)
* Required for fingerprinting (scanning) files
* [python-discid](https://python-discid.readthedocs.org/) or [python-libdiscid](https://pypi.org/project/python-libdiscid/)
* Required for CD lookups.
* Depends on [libdiscid](https://musicbrainz.org/doc/libdiscid)

* Required for the complete scripting documentation
* [PyJWT 1.7 or newer](https://pyjwt.readthedocs.io/)

We recommend you use [pip](https://pip.pypa.io/en/stable/) to install the Python
dependencies:
Run the following command to install PyQt5, Mutagen and discid:
pip3 install -r requirements.txt
The binaries for Python, GetText (`msgfmt`), `fpcalc` and `discid.dll` have to be
in the `%PATH%` on Windows.
Installation using pip
----------------------
The recommended way to install Picard from source is using pip. After installing
the dependencies, you can install Picard as a pip package by running:
pip3 install .
To start Picard now you can use:
picard
To uninstall Picard run:
pip3 uninstall picard
Installation using setup.py
---------------------------
You can also install Picard with `setup.py` by running:
sudo python3 setup.py install
This will automatically build and install all required Python modules.
On Windows you need to have Administrator rights, but don't put `sudo`
in front of the command.
To start Picard now you can use:
picard
If you want to be able to easily uninstall Picard again, run `setup.py`
with the `--record installed-files.txt` command line argument. This will record
all files generated during installation into the file `installed-files.txt`.
sudo python3 setup.py install --record installed-files.txt
To uninstall Picard again simply remove all the files listed in
`installed-files.txt`, e.g. by running:
rm -vI $(cat installed-files.txt)
Running From the Source Tree
----------------------------
If you want to run Picard from the source directory without installing, you
need to build the C extensions and locales manually:
python3 setup.py build
python3 setup.py build_ext -i
python3 setup.py build_locales -i
And to start Picard use:
python3 tagger.py
Running the Test Suite
----------------------
To run the included tests, follow the instructions for "Running From
the Source Tree". Afterward you can run the tests using setup.py:
python3 setup.py test
Packaging
---------
Picard supports packaging binaries and uploading them to PyPi.
To submit a package run:
python3 setup.py sdist
twine upload dist/*
