-# Archspec (Python bindings)
-
-Archspec aims at providing a standard set of human-understandable labels for
-various aspects of a system architecture  like CPU, network fabrics, etc. and
-APIs to detect, query and compare them.
-
-This project grew out of [Spack](https://spack.io/) and is currently under
-active development. At present it supports APIs to detect and model
-compatibility relationships among different CPU microarchitectures.
-
-## Getting started with development
-
-The `archspec` Python package needs [poetry](https://python-poetry.org/) to
-be installed from VCS sources. The preferred method to install it is via
-its custom installer outside of any virtual environment:
-```console
-$ curl -sSL https://raw.githubusercontent.com/python-poetry/poetry/master/get-poetry.py | python
-```
-You can refer to [Poetry's documentation](https://python-poetry.org/docs/#installation)
-for further details or for other methods to install this tool. You'll also need `tox`
-to run unit test:
-```console
-$ pip install --user tox
-```
-Finally you'll need to clone the repository:
-```console
-$ git clone --recursive https://github.com/archspec/archspec.git
-```
-
-### Running unit tests
-Once you have your environment ready you can run `archspec` unit tests
-using ``tox`` from the root of the repository:
-```console
-$ tox
-  [ ... ]
-  py27: commands succeeded
-  py35: commands succeeded
-  py36: commands succeeded
-  py37: commands succeeded
-  py38: commands succeeded
-  pylint: commands succeeded
-  flake8: commands succeeded
-  black: commands succeeded
-  congratulations :)
-```
-
-## Citing Archspec

-If you are referencing `archspec` in a publication, please cite the following
-paper:

-   Hoste, and Todd Gamblin.

-   microarchitectures**](https://tgamblin.github.io/pubs/archspec-canopie-hpc-2020.pdf).
