+Python 3.7 Decompiler Docker Image
+==================================
+
+This repo contains specific versions of [pycdc](https://github.com/zrax/pycdc/tree/2e76e56420493bfc0807da06a87dfdda5217a5aa)
+and [unpyc3](https://github.com/andrew-tavera/unpyc37/blob/d7dc609e8c63086dc58fc749835f7aed2482543f/unpyc3.py).
+
+On docker build, [uncompyle6](https://pypi.org/project/uncompyle6/) and
+[decompyle3](https://pypi.org/project/decompyle3/) will also be installed from pip.
+
+The entrypoint is a shell command that will decompile command line arguments
+to output 3 files:
+
+* <file>.pycdc.py
+* <file>.unpyc3.py
+* <file>.decompyle3.py
+
+We install uncompyle6 in case it is needed, but decompyle3 should be a strictly
+superior choice, so it is not included in the output.
+
+Building
+--------
+
+`docker build . -t python3-decompile`
+
+Usage
+-----
+
+This is intended to be used from the command line. Example:
+
+`docker run --rm -v $(pwd):/work python37-decompile *.pyc`
+
+The entrypoint is a shell script that will run all three decompilers on the
+passed in arguments
