+This project is no longer maintained
+====================================
+
+`Pyre`_ from Facebook is an amazing project that has a bright future and many smart people working on it.
+I would suggest, if you don't know that much about program analysis, that you understand how PyT works before diving into Pyre. Along with the `README's in most directories`_, there is the original `Master's Thesis`_ and `some slides`_.
+With that said, I am happy to review pull requests and give you write permissions if you make more than a few.
+
+There were a lot of great contributors to this project, I plan on working on other projects like `detect-secrets`_ and others (e.g. Pyre eventually) in the future if you'd like to work together more :)
+
+If you are a security engineer with e.g. a Python codebase without type annotations, that Pyre won't handle, I would suggest you replace your sinks with a secure wrapper (something like `defusedxml`_), and alert off any uses of the standard sink. You can use `Bandit`_ to do this but you will have to trim it a lot, due to the high false-positive rate.
