 == Overview
 
 This directory contains code primarily for cqlsh. cqlsh uses cqlshlib in this directory.
+Currently, cqlshlib drops support for Python 2.7. Python 3.6 and 3.7 are deprecated, making Python 3.8+ the recommended version.
 
 == Requirements

+. Python 3.8+ (for cqlsh)

 In order to run tests in a virtual environment for cqlshlib, run cassandra-cqlsh-tests.sh in this directory. It will
 automatically setup a virtualenv with the appropriate version of Python and run tests inside it.
 
-There are Dockerfiles that can be used to test whether cqlsh works with a default, barebones
-Python installation. Assuming Cassandra's source is checked out at `$CASSANDRA_DIR`. To test, first
-build the Docker image containing the barebones Python installation -
+To run cqlsh using publicly available Docker images to connect to Cassandra on the same host, with `$CASSANDRA_DIR` pointing to either the source or install directory where `bin/cqlsh` is located.
