-
-This package is a
-[Sphinx extension](https://www.sphinx-doc.org/en/master/usage/extensions/index.html)
-that makes it easy to refer to PDF files of reviews and particle listings in the PDG.
-
-## Installation
-
-Just install through [PyPI](https://pypi.org) with `pip`:
-
-```bash
-pip install sphinxcontrib-hep-pdgref
-```
-
-Next, in your
-[Sphinx configuration file](https://www.sphinx-doc.org/en/master/usage/configuration.html)
-(`conf.py`), add `"sphinxcontrib.hep.pdgref"` to your `extensions`:
-
-```python
-extensions = [
-    # ...
-    "sphinxcontrib.hep.pdgref",
-    # ...
-]
-```
-
-## Usage
-
-There are two roles, one for the
-[particle listings](https://pdg.lbl.gov/2020/listings/contents_listings.html) and one
-for the [review](https://pdg.lbl.gov/2020/reviews/contents_sports.html). These roles can
-be used as follows:
-
-```restructuredtext
-:pdg-listing:`K-zero`
-
-:pdg-review:`Kinematics`
-
-:pdg-review:`2014; Resonances`
-
-:pdg-review:`Resonances; 2018; pp. 2-4, 7`
-
-:pdg-review:`QCD; p5`
-
-:pdg-review:`PDG2015; Quark Model; p.2`
-```
-
-which will render in the HTML pages as:
-
-> [PDG2020](https://pdg.lbl.gov/2020/listings/rpp2020-list-K-zero.pdf)
->
-> [PDG2020, §Kinematics](https://pdg.lbl.gov/2020/reviews/rpp2020-rev-kinematics.pdf)
->
-> [PDG2014, §Resonances](https://pdg.lbl.gov/2014/reviews/rpp2014-rev-resonances.pdf)
->
-> [PDG2018, §Resonances, pp.2-4,7](https://pdg.lbl.gov/2018/reviews/rpp2018-rev-resonances.pdf#page=2)
->
-> [PDG2020, §QCD, p.5](https://pdg.lbl.gov/2020/reviews/rpp2020-rev-qcd.pdf#page=5)
->
-> [PDG2015, §Quark Model, p.2](https://pdg.lbl.gov/2015/reviews/rpp2015-rev-qcd.pdf#page=2)
