+Pylk: the pint GUI
+------------------
+
+Pylk is a Qt based GUI for PINT, the python pulsar timing package
+based on python and modern libraries.
+
+It is still in active development, and it resembles the pintk GUI.
+However, it holds the promise to make more advanced methods of
+interaction with PINT available to the user.
+
+
+IMPORTANT Notes!
+----------------
+
+PINT/Pylk requires `longdouble` arithmetic within `numpy`, which is currently not supported natively on M1 Macs (e.g., with the `ARM64 conda build <https://conda-forge.org/blog/posts/2020-10-29-macos-arm64/>`_).  So it may be better to install the standard `osx-64` build and rely on Rosetta.
+
+Installing
+----------
+
+Install using ``python setup.py develop``
+
+Using
+-----
+
+See the online PINT documentation_.  Specifically:
+
+* `tutorials <https://nanograv-pint.readthedocs.io/en/latest/tutorials.html>`_
+* `API reference <https://nanograv-pint.readthedocs.io/en/latest/reference.html>`_
+* `How to's for common tasks <https://github.com/nanograv/PINT/wiki/How-To>`_
